Hey thanks for the replies. I am definitely going to spend some more time in the bicycle shops. I am also looking at used bikes on Craigslist, but I am afraid of getting something which is not for me. I really want to take off with this. So, I want to minimize chances of getting something that's uncomfortable, something no well suited for me etc. I'm thinking I'll spend something like $400 on the bicycle itself, but maybe I'm being too frugal? I know that people spend way more on new bikes especially specialized ones for serious riders. I'm hoping to become a serious rider myself, but we'll see. I'll post pics when I make up my mind, though I might come back before buying to ask more questions if I get bowled over in the bike store.
