What record cleaner is the most bang for the buck??

I would not use Amazon as my first filter.

Look at VPI record cleaners. That was my first one, for over twenty years. Really loud and large. But did a good job.

My second was a German Nessie. I got mine around $3,500. Well worth it… very quiet, small, beautifully constructed, and more fully automated.

In retrospect, it is something you are likely to, have a long time and spend hours over… a good one is a good investment. Some of the folks with cheap ones put ear plugs in to get away from the noice. Wish I had thought of that with my VPI.

I use the KAB EV-1. It's like the top section of a Nitty Gritty record cleaner that you hook up to your own vacuum cleaner. I like that it sucks the waste water off the bottom of the record rather than fighting gravity. It only costs $149. It's sold by KABUSA.com.

I’ve owned a Disc Doctor and a Degritter.  The Degritter was the better value because it more fully cleaned a record and did so with little effort on my part.  For neglected records I use DD first and then the Disc Doctor on Heavy Clean.

Record Doctor!

Look at the Keith Monks Prodigy, I believe they start at $1000 and go to around $2000. No Re-Contamination and quiet and fairly quick.
