Help? Anyone?

Since we'll soon be getting a lot more room (*insert excited squeal here*) we can finally get into doing some of the things that we've talked about doing for years, but never had the room for.
Like printing our own t-shirts and stuff like that!
But i know nothing about these things, so i thought i'd ask your advice, oh wise blog readers.

There's a ton of different screen printing stuff on ebay, everything from the very hobby-like to the very pro looking stuff and i'm... well, i'm confused.

All advice is welcome, comment away!
