Me, I just slip my Touch into an old plastic hard drive envelope, with a piece of corrugated cardboard that's wrapped in duct tape to protect the screen. [the duct tape's optional, but I don't happen to have particularly good scissors, so the edges were all ragged and prone to dropping off bits and cardboard dust - not good when that crap gets into the opening around the screen]
It's cheap - and sturdy enough to protect from damage while my Touch is in my backpack or my back pocket. Also doesn't double the weight of the Touch like a decent cover would. Doesn't look good, but so what? I'm not one of those types who has to make a big show out of being seen taking it out or putting it away, so it's not like anyone's going to actually notice.
