Now if I could just get a price for Boneyard Station from Shadow Shack! :)

YES! Thank you. The FPs are such a pain for everything. 

I have been looking for another ship system to "plug in" but everything I have seen changes the game too much.

No guidelines there, price is dependant upon the overall condition of the salvaged warship (re: drifting hulk) . ;)

The Melinda McCoy from that game (obliterated by the Malthar in Dramune Run) was an otherwise salvageable hull that could be restored to its former 50 hull points and had a fair amount of allocated space for weapons/defenses compared to civilian craft (but in no way could accomodate the original armament) but was otherwise stripped to the bulkheads. The buyers basically paid for a military warship hull design and had to redesign/refit/retrofit it from the ground up. Since all the allocated space from the former military hardware was vacant, it left a fair amount of space for a cargo hold (not the full six units, mind you...IIRC it ended up with a four unit main hold and a half unit auxilliary hold) while retaining several areas for a decent selection of weaponry.

The light cruiser UPFS Courageous on the other hand (which wasn't available at the start of the game but a "move up" option I had available for later on) was victim of sabotage and had the magazine explode from within, nearl shearing the hull in two. Once the UPF was done with their investigations it had been stripped and demilitarized so it was basically a size 12 warship hull that had warship hull point capacity but otherwise would have been subject to all other civilian rules. The price for that would have been about what the McCoy remains were sold for...because there was much less of the original design left by the time the scrap yard acquired it (versus finding the McCoy drifting before the UPF did, salvage laws being what they are).

Then on the other side of the sales yard, there were near-complete vessels that had been worked on but needed finishing (as opposed to the partial ships & hulls that those two warships fell into). The pirate assault scout and corvette that was available there had asking prices surpassing brand new civilian ships of the same size...after all, best wishes to the spacer wanting an ADF:5 civilian scout ship or a MHS:5 cannon stuffed into a size four civilian hull.

Yes, exactly. I'm actually trying to figure out what certain things would cost, in addition to ships, like a ship yard or space station for example. I"m also trying to figure out what a space ladder would cost, both using an asteroid as an anchor, or a space station.

I'm imagining a race on a world that has always looked up at the "island in the sky", a moon that never moves, and thinking, "we must go there".  The natural desire would be to build a way to the place.  Of course history would be full of failed towers, but the magic behind such a notion would remain.  Eventually they develop rockets and get there.  Then the efforts for the mythical ladder would resume.

That's one thing that's kind of missing, as the PCs get more powerful (and nearer to retirement) where the PCs can build stuff on all of these backwater planets that they saved from the Sathar Onslaught. The KH rules do ok with the mining and freight hauling stuff, but how much to build a building? Or carve out an asteroid? Etc. So I'm trying to figure some of these things out. My kids have hired a crew to run freight in the gullwind and picked up a regular charter, and I'm actually considering them having control of a backwater planet off the edge of the map in unclaimed space as a kind of stronghold. 

The alcazzar module points out that the operation there cost 5 mil to set up. That's the closest thing I've seen. It would be cool if there ws some sort of standard building cost sheet or something. But what metric would one use to create that? It seems as though the template for ships hulls would be a little high. But there would have to be life support, airlocks, a power plant, etc. 

Have any of you guys ever dealt with this stuff in your settings?

Just for the record, there is no corellation. There isn't even a corellation between the SF credit and the 1982 dollar. The prices in Star Frontiers factor in availability to the player characters. That's a variable that doesn't fit into real world economics.

The cost variances in the magazines or elsewhere tend to be because of inexperience with how to calculate them. The higher costs are more likely given the math provided in the rulebook. Though the lower costs may be only calculating for civilian ships. The only way to make sure it's right is to recalculate the ship yourself, considering whether it is civilian or military, based upon the HP in relation to size. Make sure to calculate all the equipment and programs, and you should come to the correct cost.

Perhaps the ship provided with the cost should be given identification as either "civilian" or "military", so that the cost can be better understood.

Also, any comment from the gang on the subject of other buildings? I'm trying to figure a baseline amount here. For example, if there was a structure needed on a planet that was heavy duty and required life support, would space ship hulls be a good metric? Then work backward from there; 25% to 50% if the building was on a planet with an atmosphere and/or was thinner than the 200-250 structural points of a ship's hull...
