Folks, here's an update to this wonderfully useful thread.
On Thursday, I stopped by Wheelworks, as I do every couple of weeks, to pick up a few things. While there, I shopped for a short-sleeved jersey. I found little that was different from what had been there for weeks, and that selection was unsatisfactory to me. Granted, they have some gorgeous stuff if you want to pay $100-200, but that is way beyond my reach right now. I demurred.
Yesterday, my wife and I headed out to REI Natick for some camping gear (we'll be at Bar Harbor end of July for a week!). While there I shopped for jerseys. I hadn't been to their store before, b/c this thread led me to stick with Wheelworks for clothing for the last few months. I have to say, I was very impressed with the jersey selection on the low-to-mid-price range, and the quality was quite acceptable, maybe even better than acceptable.
I can't speak to other clothing needs at REI (tights, shorts, jackets, etc.), because I haven't looked yet. But for those of you on a budget and looking for (at least) jerseys, do yourself a favor and head out there. I don't have half the miles that most on this thread do, but it looks to me like jerseys are one item you can scrimp a bit on (especially if you also have a few nice ones). The low-priced ones have lasted just fine for me and my friends, look fine, and keep us plenty cool.
