I can't speak for the smaller Bridgestone's, but that sounds like a good price if it's basically all there.
Even better if it has a title. If the gas tank innards aren't too rusty, it probably wouldn't be too hard to make it run. My first guess would be oil or corrosion on the points keeping it from generating a spark at plug. Even simpler might be just a bad spark plug. Buy the bike and hang around here awhile.
