Hi, I'm about to buy a new bike and i know nothing about the specifications. i want to the know difference between the 2011 Jamis commuter 2 (originally around $500, on sale for $420) and the 2011 Jamis commuter 3 (originally $800, on sale for $560) which one is better and which one is more worth the price? Also, i want to know what you guys think about the 2013 Trek 7.2fx which is $590 and not on sale. would you prefer, the trek or the jamis'? i want to get the trek more because it looks nice and it feels lighter, but the two jamis bikes are on sale and since its the end of the summer i want to take advantage of the sales. thanks!
