I recently used StitchTek to get shirts made for my VMware User Group meeting. They were very helpful helping to pick out the design that would go on the shirt, as well as helping us pick the right shirts to use to fit our budget. They are always fast at replying to emails and great to deal with. At the end of the year, I plan to contact them again to get hats, mugs, or something else made up for us to give away! :)
