There was one in Canada on eBay recently that went for under $20K, but you can get from England on the cheap fairly often. The key is to import them under the NHSTA "Temporary Race Car" category which let's you keep them for up to 5 years before either exporting back out or destroying it. I almost bid on an '86 Sierra 4X4 but couldn't line up the brokers (Import & Customs) in time for the deal, but it sold for $230 USD. I almost cried, as the drivetrain fits right in the 3-door shell. Oh well, I'll just keep looking...
