@benanders understood. I personally find a record cleaner a luxury investment. I can go to a local stereo shop and use their VPN for 50 cents per record which I do 10 records at a time, every other month. It would take 500 records to recoup that investment, at this rate: 9 years for me :) - when compared with the record doctor.
So I'd spend that money elsewhere. I would always go speakers/source/preamp/amp
