Don't underestimate the manual Spin Clean machine. Google it. I just purchased one (actually, my wife and kids did for my B'day), and at $80 more or less, it's remarkable. I'm not saying it'll do the same as a vacuum machine, but I can buy a lot of bargain basement $1 specials for the $400 plus I saved.
The albums I'm mostly buying these days are quite dirty Goodwill specials - dirty enough to gunk up my AT440MLa stylus on one or two songs, and that's AFTER a hand cleaning and use of anti-static brush or gun. But after cleaning with the Spin Clean, I don't get any stylus buildup after playing 10-20 of these formerly dirty LPs. Both the previously hand-cleaned and ones I haven't touched are remarkably clean. Except for some extremely dirty ones, the Spin Clean reduces surface noise to almost nothing, quite a dark background. I simply can't believe the difference.
OK, just my $.43 for those on a tight budget. It'd be interesting to see a side-by-side comparison of Spin Clean and NG or VPI or the others.
