I just went through the same decision process. At the bike shop i was at there was a 2011 quick 4, and a 2010 quick 3. About $190 difference. I rode both and honestly like the quick 4 a little more. The components on the quick 3 are obviously of better quality though. I would recommend riding both. the Quick 3 is significantly more stiff and a rougher ride. I didnt really care for the stiffness. With that $200 savings I bought some smaller conti gatorskins, some bike maintences stuff. I am happy with my purchase.
