Well, I have to say I'm very pleased. I was recently contacted by custom t-shirt company ooShirts who offered, in exchange for a mention here on the site, some basically free shirts. I was skeptical at first, but have to say I'm pretty happy. The design interface on their site is easy to use, and the turnaround time was quick as well. Best of all, they did great work with some dodgy (at best images) I sent to them.
The only bad news is that I only had four made...I'll have to figure out if I'm going to be making more. I doubt there's much demand for these but they are pretty cool!
