I agree with GT. I hear a lot of bad stuff about Zoom all the time, but the 123 and its big brother ...234 actually sounds really good for that kinda money. We spent a couple of hours programming the crap out of a ...234 and it held up amazingly well. I then played around with the 123 in a music store and the sounds are very similar if not the same.
There's a new one out now i think, 323 or somthing. I saw a picture and it has a way better display and most certainly a bunch of other new stuff. Haven't heard it yet, though.
The only thing i had a problem with was there're only two outputs. You can get around that if you're a bit patient, but it's a bit time consuming.
