My preference is the VPI 16.5, principally if you have a lot of older, filthy vinyl to clean, as you can really give it a good scrubbing with that brush. Easier to use, too, as Alexc notes. My brother is quite happy with his Nitty Gritty I gave him, though, so you probably can't go wrong with either, just depends on how much used vinyl you obtain. The Clearaudio sounds interesting, but given the inevitable importer's mark-up I think it will probably be at a much higher price level than these two machines.
