I like what I'm hearing about Zazzle so far. The first few shirts I bought from CafePress seemed like decent quality cotton, but the last two that I got are very flimsy. If these are the standard weight shirts that they're using now, I'd hate to see the "value" shirt. Increased design flexibility is a huge plus. My swag may have just found a new home!
I just ordered my NCBC logo black shirt from Zazzle and it came out fantastic. I too moved all my stuff to Zazzle. I've been going crazy over there making stuff.
