yeah i used to run one of those. it would be a decent cheap pre/AD, in the same category as the edirol but it only runs on AC. core sound sells a power pack for it but it almost doubles the cost of the unit. i had very good results with using a power invertor pack at target ($20), included 2 6V SLAs wired into a 12V with power invertor, and even a light attached to it! you can find it in the camping section. core sound said they had lots of problems finding a reliable power supply for it, increased noise and whatnot, but i never had a problem with my power supply. i even ran some tests, comparing noise levels between the power pack and the wall wart, couldn't tell the difference.
i have some tapes if you want to check them out (391 -> Duo -> D8)
