Any opinions on Record Doctor VI?

This works incredibly well:

Pretty cheap too.

Probably not relevant as I might used the Record Doctor VI to rinse off any remaining Tergitol surfactant after the Degritter.

+1 @mofimadness - ultrasonic record machine cleaners clean vinyl records best, the Humminguru is a great high value choice -  proven by many user reviews including here on Agon.

So you have two hundred bucks in a project you put together and for another 150.00 he can have a professionally made machine? I'm not knocking your skills or ingenuity here, but I also don't think the RD VI is overpriced when you compare the two.

I have owned the Record Doctor VI for close to two years now. I have had no problems with it. It seems to be built sturdy enough. It is loud when the vacuum is sucking. But what vacuum that supplies enough suction isn't? I think that it is a good deal as far as record vacuums go.

I owned the Record Doctor version that was motorized and cleaned both sides simultaneously.  It was wonderful and compact.  After about a year I headed into the bathroom where it was sequestered and found it dead as a doornail.  Now it's discontinued, because of this or some other reason I don't know.  Prior to that I had a VPI 16.5 from the mid-eighties until a year or so ago, at which point it died.  Frankly, it was an inferior machine to the aforementioned RD one.  The two-sided vacuuming deal was fantastic, and the RD price was really, really good.  Most recently I'd used those devices as prep before going into the Degritter, then later went to just the Degritter with the MoFi solution, saving the RD for really hard-to-treat records the Degritter couldn't fully solve.  Maybe there's a better solution to use with it, but I found foaming to be a potential problem with the ultrasound.  I need a replacement for the old RD machine, so there's the RD VI and the model ProJect makes, which at least is motorized but way more expensive.  I'm not excited about turning the records by hand, which seems inefficient and I am spoiled. $1000 for the VPI is, frankly, absurd.  $500 for it decades ago was pricey too, but I guess there's a limited market for these things. I think for most people the RD VI makes the most sense.  I don't have the space for a fully manual setup.  Any ideas?  BTW, what's the ideal solution to use in an ultrasound machine like the Degritter?  Back when I was using it as a secondary device I just used distilled water, but not now.  There are so many solution out there.  Whatever you use, it should effectively clean, remove completely, and not foam to where it can foul up your ultrasound's sensors.  And there's one other thing that's interesting:  I started collecting records back in the middle sixties, and by the middle seventies was cleaning all of them, Discwasher or whatever.  Recently I've been going back through those old records (I would put the cleaning date on the sleeve).  They alll sound pristine, generally not needing recleaning. So there you go.
