Welcome! I would advise also that you should set your budget and then get the most bang for your buck. I don't know how everyone else here feels but a lot of price is determined by the name on the downtube much like the name on the tennis shoes. If it says Jordan on shoes they are 100 bucks more... I am a bigger guy weighing in at a whopping 240 at 6'0" which I am working on getting down lower but I ride a full carbon fiber. In interest of full disclosure I haven't put too many miles on the bike yet but it rides just fine. Find the best bike that you can for your money and you won't notice components much as a newer rider. I got a deal on craigslist like mentioned above from a guy that rode the bike 64.9 miles and I paid about half price for it. Good luck with finding a great bike and get on the road as soon as you can.
