@Bonesy Jonesy-
On Next US RCM- I'm not sure. I was kicking around the idea of an industrial grade machine.
@Neil.Antin had at one point brought up the machines made by Zenith, which are typically factory line type for industry. They make a bench top. I had talked to the owner many years ago about making me a custom machine, and he wasn't interested but they do make a bench top. As Neil has pointed out, it may be overkill for my needs, take up a lot of space and then there's the cascading bath if I use a surfactant.
I think the new KL with the remote tank is pricey for what it is, I'm not sure about the calibre of the filtering and the fact that it has to use tap water to trigger the sensors gives me some qualms.
The DeGritter seems to be a popular favorite, my friend
@Albert Porter swears by his and he's had 'em all. Short answer, I don't know.
On fluids- I found the Monks gummy and was concerned that it might actually be masking noise- not a bad thing in some cases, but not what I want. Even Art Dudley (RIP) commented on the sticky residue it left on his brush.
I use a fluid concentrate from the old Hannl company out of Germany which is no longer available for a light wash, and AIVS #15 for deeper cleaning. I always rinse.
One downside of using surfactants-- which the Zenith guy first convinced me significantly enhanced US cleaning effectiveness, is removing them. That's why I don't like forced air drying with a US that uses a surfactant.
The combo of the Monks and the KL are synergistic. What I'll replace the KL with is still open, if and when. As to the Monks, it will go on the Viking ship funeral pyre with me when they set it afire and launch me to sea, wearing horned helmet, playing Steppenwolf at 105db.
