Nice projects and products from the online sites!
i went through a phase a few years ago of making lots of shirts myself, using iron-ons. Quality tees available at craft store for $3, and then just the ink and iron on transfers (~$10 a pack), so each shirt probably only cost$5 to make. They've held up okay, although you can't really throw them in the dryer (lest they crackle and peel).
I made a couple other Underworld shirts ( a blue one with the beaucoup sphere and the text "The silence is pushing it around. A little sound in a little amp" was one of my faves). here's the one i wore to the NYC show, straightforward text that i cut out and ironed on:
