About the same price as a Boss RC-300.  And as Edwin alluded, it does appear to have a lot of capability.

I have a Boss RC20xl loop station that works real well. Better than I do, anyway. I've used it on a couple of gigs. A guitar player I used to work with in jazz trio gigs used one to great effect - laid down a chorus, soloed over it - and made it seem effortless. It sounds great, I just am techno-challenged.
