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

I use my Record Doctor mostly on new records and new used records. Once they are cleaned I use a carbon fiber brush. 

Spinclean for cleaning immediately prior to playing. VPI for real ceaning.

Another vote for the HumminGuru. I purchased two, one for wash and one for rinse.

Far better than my VPI 17 Pro with Disc Doctor brushes and fluids. I only used the VPI to spin the disc during cleaning & rinsing and finally, removing the rinse distilled water with the vacuum.

The Humming Guru does a much better job.

I've also owned the Kirmuss and it was just too much of a pain for me and I found that the extra effort wasn't worth it to my ears. Also twice the price of the HumminGuru.
