I'm going to look into one and compare it.If you can, get a digitech trio. You play a few chords and it gives you bass/drums to solo over the chord progression. It feels more like playing with a band than just looping over your own guitar again. I picked up one a several years back for 60-70$ - they've been out of production for a while, you can probably get an old one for cheap.
