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....

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.

This is great. Let's stay in the loop on this. BTW, that DIY thread is 'only' 145 pages. Many thanks again, Rushton, and to DGarretson for raising the topic of DIY in this context. 

@terry9 : extremely helpful on several fronts.
I don't want to hijack @soulbrass 's topic about reliability of the ADS, so perhaps we can start another thread on the DIY approach. 

Soulbrass, at least from my experience with both the ADS and KL, the commercially branded "audiophile" solutions like the ADS and KL are both pretty well thought-out machines that are effective record cleaners; that Robert Stein who brings ADS into the States has been very good about supporting the ADS here;  that some of the customer problems of the ADS may have been due to the fact that the machine was a pretty innovative, early effort to address a " complete one step solution" for record cleaning, but with the rollers and computer functions to activate it, is more complex than a plain vanilla ultrasonic bath. (I gather that the "Pro" version embodies improvements, but haven't used it). But, to me,  part of the answer to your question about "what next"  is a digression into DIY, which isn't just about a cheaper alternative (though it can be) but a more effective one, for some of the reasons stated. You might consider exploring that path as well. 

Well, your existing unit is dead, and costly to repair, I gather, so if the price difference isn’t crazy to trade in on a brand new unit, assuming transferable warranty, you could always sell it, no? I don’t think enough time has passed to make any meaningful assessment of the longer term reliability of the new "Pro" unit. (I also don’t know if some of the industrial/medical type units are cheaper to repair with replacement parts reasonably priced and available for repair in the field, rather than sending back to the factory, a question that I have now added to my own list for due diligence on those).
