None of the DIY units dry. You have to get up to about two grand for a US system with a dryer. For me, I would use this for records that didn't respond well to vacuum cleaning and I would vacuum clean them again after the treatment. With Carl's US system they come out wet, and I just give them another quick clean after and I can tell you that the ultrasound definitely gets some albums much cleaner than just the vacuum.
I figure that perhaps the vacuum can't get off the 40 years of baked on deposits, but it can get off the tiny bit of cleaning fluid left on by the US. If we can find a way to keep this under $300 with the shipping, I'm all over it, and you know how cheap I am.
Also, some people don't use any chemical in the US, just distilled water. I guess the sonic waves are like sand blasting and no chemical is really necessary (but I haven't tried that, I've only read it). I believe Carl uses a few drops of TergiClean in his US tank (hopefully he will correct me if I'm wrong).
