I like the Hercules. Problem is that even if the guy gives you the bike for free, it will cost more to get it road worthy than it's worth. But, if you could get it for like $15, then if you find that it's not worth saving you might be able to salvage the hubs, shifter, bottom bracket, maybe the fork and the frame. Lots of work for little probability of success or return. The Ross actually looks like a nice, decent bike for tooling around and it probably doesn't need much work. Might be a good deal.
