Recorded Cleaning Machnies

I'm going to buy a ultra sonic record cleaning machine.  I am looking seriously at the Degritter MK2 but I just found the Isonic CS6.1-Pro Record Cleaning System, which has the advantage of cleaning 10 records at a time.  Anyone have any experience with either of these?  Comments?  I have a lot of records (like most folks reading this I suppose) so cleaning 10 records at a time is a big deal.  There is a price difference, but frankly, that is not too big a deal given what I am buying here.
