It's also a loop sampler with 4 and 8 seconds loop samples.
It has 5 effects loops.
The only place I found prices quoted was on Ebay and the two used units I found there were going for close to $1000. It's the kind of unit that ends up in production studios far more often than in guitar racks. For what most street musicians are going to need in a delay it looks like serious overkill unless you often use long loops as accompaniment and then solo over yourself.
Even for serious loopers, (like me), there are better choices, like the Echoplex Digital Pro. It is more for the studio, although Robert Fripp uses 2 of them live.
