Audio Desk Systeme RCM - what's been your experience?

I think the semi-DIY route @dgarretson described is not only more cost effective but offers more flexibility, particularly if you are willing to forego some of the convenience of the "one button" fully automatic audiophile models. The commercial audiophile machines (and I have owned both the Audio Desk and KL) have some limitations compared to what you can achieve with the semi-DIY route.
I am in the throes of planning another machine (not for resale, just for my own use).
Dgarretson-can you speak in a little more detail about the pump circuit with filter? One of the desirable features may be the ability to filter the water in the bath between cleaning cycles. I don’t know if you are using any kind of surfactant to enhance cavitation effect. I’m still trying to sort out the filtering issue as it relates to using a surfactant, since I assume the filter is designed for particulates- and I don’t know how the surfactant impacts the filter's effectiveness. (This is a work in progress for me- still learning). Thanks....

The pump solution dgarretson describes above is what I'm doing. You can see some pictures and video at this link to the VPI thread discussing this, which contain links to the information in the very long-running thread on the diyAudio forum:

The Little Giant 1-AA-OM pump has been discontinued but I was recently able to purchase a new old stock pump from this eBay seller who apparently has several:

Let me join in here with my experience of the Audio Desk.  I have had a machine for a little over 4 years and have cleaned more than 1500 lp's. It is a very complex machine which makes it simple/great for the user but it does mean there are lots of moving parts/mechanisms.  I did have a bump in the road a while back when the lp's stopped turning and sent it in to the US Distributor (Ultra Systems).  I was bit worried as the machine was out of warranty at that point, but they found and fixed the problem
 ( needed new o-rings) and had the machine back to me within 2 weeks with all new barrels and a new filter and could not have been nicer/more professional.  I am sure that eventually the machine will break - all mechanical machines do - and at that point, I will likely get another one as I can never go back to playing lip's that aren't pristinely cleaned.

Thanks, both. That thread on DIY is about 230 pages long now! I've been slowly working my way through it, and have been doing a little additional research and inquiry on the side. My interest is less about cost cutting and more about improving results: a set up that allows the higher frequencies, permits the use of some sort of surfactant, is robust, takes heat into account and can address filtration of contaminants in the bath between cycles. I  can do a reagent water rinse and dry on the Monks, rather than forced air. I'm not so concerned about stacking multiple records for one cleaning cycle. I'll take a look at the VPI board as well.
