For the past few years I have resisted the urge to buy a jersey. I have worn Under Armor, Stay Dri and Dri Fit shirts that have seemed to work well. I think my hesitation is from not wanting to be 'that guy'. The one who get's all George Hincappie looking just to go out riding. That and not really knowing how a $70+ dollar jersey will effect my riding vs Under Armor (which I get through work).

Is there a difference in quality/performance here? Or a less expensive place to look?

To be honest I would kind of like to find an old USPS team jersey. I know it kind of goes against what I said above but that's another story. lol
