There are a ton of those out there. I've owned three myself. Usually getting them working by re-burning bad roms and the like. I wouldn't mind having the board so I can stick it in my new project. I'm collecting parts for a muti-JAMMA setup.
That said, I'm not a leech so I'll tell you depending on location and how fast you want to sell it, you can get at least $350 for a working Hangtime.
If you want to trade some parts for the board send me a PM.
