I agree with Abstract7's comments. No doubt that the VPI 17 is by far the easiest to use, but it is also much more expensive than the lower-cost NittyGritty machines. If you either own or have to clean a large number of LP's, you will certainly appreciate the convenience of the VPI 17. On the other hand, if you only clean LP's occasionally, then the NittyGritty Model 1.5 will work just fine -- and cost a lot less. (I have no experience with Record Doctor's cleaning machine.)
I have been using a NittyGritty Model 1.5 for many years, and while it is more cumbersome to use than the automated models made by both VPI and NG, it still does a good job of cleaning LP's.
