This is the main part of my rig right now. I love this thing, I can get a wide variety of tones out of it, and I use the Gearbox software to edit those tones. This I also bought off of my brother. It does take some tinkering to get that sound you want, but I eventually got it.

EDIT: I now use this totally as an effects unit for chorus, delay, octaves, wah, etc.
