I would say it depends on what you were gonna do with it. Do you need one for your project? Or are you gonna bail out of it in a couple weeks and resell it. I would say that the open market would allow up to $500 on something like that. If it had pistons they would probably need to be replaced anyway, so that is not really an issue. I know a five speed gearset would go for $500 on the open market at least. $200 would be awesome, but $500 would be reasonable too.
