KAB EV-1 External Vacuum Record Cleaning Machine

Has anyone used this record cleaning machine? It is essentially a basic Nitty Gritty manual design but with a different box, that requires being connected to an external vacuum. Very reasonably priced ($140). I'm thinking of using it for the vacuum drying stage combined with a Disc Doctor setup for washing. Any thoughts or experiences?

I haven't used it, but I was thinking about getting one, until I made my own machine. I think it would be just as good as the regular Nitty Gritty, and alot cheaper.
