I have a Cinemag 1254 based SUT built by Ned Clayton on eBay. I find it to sound fantastic, and should be similar to one of Bob's Devices but is much cheaper. It has 4 gain settings for ultimate flexibility, and 3 ground settings for the most quiet blackest backgrounds you'll ever hear. I find detail and clarity and bass drive to all been kicked up a notch as opposed to going straight into my phono pre, which is quite hissy at high gain levels. Now my MC setup is dead quiet, something I'm not used to, and paired with my old Koetsu Black, I am in vinyl nirvana.
