Why don't you buy one from GC or Musicians Friend? Return it of you don't like it.
I didn't know whether I wanted to keep my Bass Pod XT Live or go with the Line6 M13 stompbox modeler. I bought the M13 at GC, tried it side by side with my Bass Pod XT Live for a weekend, then returned it on Tuesday.
Credit card was credited and I knew what I wanted. (Bought an X3 Live

)
