Hi Night Owl......it's called a "Riff-O-Matic" (corny, huh) made by Akai and sells for about $149 U.S. I got mine through an on-line music equipment company called Musicians Friend or http://www.musiciansfriend.com.
There was a thread called "Software To Slow Down Music" back in July of last year that talked about some stuff you might be interested in. That thread was where I initially posted the info about the Riff-O-Matic....or http://www.mudcat.org/Detail.CFM?messages_Message_ID=94357
The thread is here or http://www.mudcat.org/thread.CFM?threadID=12173
