Was it last year that Bicycling Mag put the Trek 1000 as the best road bike for the price? It has a msrp of $709 on the website, and that's a 2007. It comes in men's sizes and WSD so your chances of finding a fit are greater. You may find last year's model cheaper. From postings here, I know that bikingmomof3 loves hers! And you would have a(n) lbs to help you out or answer questions and make adjustments. May be a tad more than you want to spend, but worth it in the long run. It will hold it's value (for resale) better in case you decide to upgrade later. Maybe I should restate - for when you definitely decide to upgrade later.
Trek 1000 (I hope)
