Well, having cleaned the first few records last night with my brand new Record Doctor V, I'm happy to report that it works as advertised! LPs come off the vacuum with a nice glossy surface and play with none of the "first-play crackle" that seems to be a part of the Spin-Clean experience. I'm still fine-tuning my user technique, but turning the disc slowwwly over the vacuum definitely brings the best results. I have no significant issues with how easily discs spin, and I have no need to buy the upgraded KAB platter. I have yet to try it with REALLY dirty records, which is one area in which the Spin-Clean excels. If it can match the Spin-Clean's performance on thrift store records - and if I can get it to work with 45s (which I believe it will, but haven't yet tried) - then my Spin-Clean will likely end up in the Classifieds. In short, assuming that it's built to last, I declare Audio Advisor's Record Doctor V a very worthwhile purchase for $199. I do not see any real advantages over the more expensive RCM's aside from the powered turntable on the VPI and the like, which is not worth the extra $$ for my needs.
