Thank you guys for your answers!
at langsmike: Ok, I will try to check more carefully on a local shop. I'm in Cambridge (Boston), but the only one I went had not so many bikes, and they were ultra-expensive. I'm really skeptical about it, so if you have any suggestion, please give it to me =) And if you could please make some points about the bike you listed, or other that you think will fit, and the ones I posted, that would be great. Not just that they're not int he same category (or the very important point about customer service), but more about parts. Thanks.
at underdog: I will. I actually tried it, too, but I couldn't find any interesting, and I think it's very time consuming. Also, I think I'm not expert enough to spot the deal, and to make sure that they're not fooling me. All this makes this option less favorable to me. Unfortunately!
Anyway, no suggestions on the type of bike at all? Also among ones that you know.
