stringreen, did you buy all or most of your records new? I believe that can make a big difference, particularly if one is careful about how they treat/handle their records, which I suspect you may be.
But I've become a believer in US even without yet owning one, simply based upon the overwhelming positive comments I've read on line.
My first record cleaner was a Nitty Gritty but it had the manual record rotation. I soon grew tired of that and bought a VPI 16.5. That changed my whole attitude about record cleaning. Now I plan to get an US device but will keep my 16.5 for rinsing and drying.
