Last week, I bought a Diamondback Response. I rode it once and everything seemed OK. I rode it again and, to make a long story short, the thing was screwed up bad. I returned it, the mechanic felt bad for giving me a POS, and he gave me a great deal on the Response Sport and threw in a discount on some swag.
For $338, I got this bike:
As far as I can tell, it usually retails for about $440 - $450. I love the bike and the price, so I am happy.
