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

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.

To counter a post above, IMHO 99.9% of people don’t take record cleaning seriously enough.
