haha thanks phatal. i'm here now. yea i run a casio DA-7 portable dat, not the DA-R100, but i got it for a steal, i almost don't wanna say how much i paid.. but it didn't work just so you know. I got it for 40 off ebay, and it was like 350 to fix it i beleive, but it needed a lot of work, according to prodigital. and has worked fine for the last 10+ shows, except my heads were dirty once, but that was an easy fix.
i'd recomend checkin to see if you can get parts for it, check
http://www.prodigitalinc.com/ and see if they can hook you up. good luck. peace.
