There are a lot of really cool dist-pedals around. I'm not very happy with Boss-pedals, but they are really cheap. The DS-1 i a nice one, but it sounds more like a bumble bee. But for that prize, I guess it's one of the coolest you can get.

Others: Z Vex, Xotic, Dunlop, Jacques, Visual Sound, etc. There are a lot of cool pedals out there. But, the coolest is to make you own :D try www.diystompboxes.com
