Why are record cleaners so expensive?

Cedar- good post- sometimes i view record cleaning as a task to be dreaded, and other times, I look forward to it and can actually enjoy the process. I've had both commercial ultrasonics- the Audio Desk and KL and have used them in combination with vacuum machines, like the Monks. The best results I have obtained have come from washing a pre-cleaned record in the ultrasonic, and vac drying it on a point nozzle, like the Monks (or Loricraft). The vacuum seems to be more effective than forced air drying  in removing the last iota of crap from the grooves.
So, the notion of a DIY ultrasonic makes huge sense to me, not only as a cost savings, but because it enables you to remove the record before the forced air drying cycle (something that isn't really possible on the Audio Desk and, while possible on the KL, isn't recommended by the manufacturer). 

whart:,

One can remove an lp before the drying cycle starts on an Audio Desk. But, Why?

Vacuuming dry is effective but has the deleterious affect of infusing static electricity back into the clean vinyl record.

Cedar: I wholeheartedly agree that one has to (enjoy) the process. Otherwise, it is failed effort over the long haul and if you dread cleaning, the lps will suffer, so will your listening pleasure.

Slaw- really? When I had the Audio Desk, I don't recall any way to stop the machine before it goes from wash to dry- yes, I suppose you could just pluck it out before the drying cycle started- then, the machine would continue to dry with no record in it? 
The why is a different matter. No static using a Monks (or Loricraft). And it sucks out the stuff in the grooves, rather than blowing air on the record. In more than a couple of instances, this method helped me remove tracing distortion on records that I would have attributed to groove damage. 

@cleeds  No, my mind wasn't made up beforehand, but yours obviously was insofar as the histrionics of your replies.

I get it: you're passionate about a vinyl cleaning machine. I'm ambivalent, really. If I had 3000 lp's, maybe I'd invest in one, as Mapman suggested. I don't know if I'll ever have that many of anything (except grains of rice), so I probably won't spend $3K on an Audio Desk, seeing how I don't need one.

And thank you for your words of wisdom re: Fijian vacations. As someone who has taken a few of them in my life for $3-5K, I cam attest that they are indeed one of a kind experiences that didn't involve run-of-the-mill resorts. Perhaps you should get off the beaten path more often -- before you face the vinyl curtain.

Anyway, thank you to the rest for all the technical info about cleaning machines. I know my little Spin-Clean is probably the equivalent of an Easy-Bake Oven when compared to a really good stove; I just wanted to know why and if the cost was justified.

whart,

You are correct. One can "pluck the lp out" before the drying cycle, (and then simply press the off switch. Yes, really.

I've never used a Loricraft but I can surmise that anytime two differing components meet/touch, there is some sort of reaction. If one steams first, as do I, then there is little to no crud to be sucked up in the first place in the later steps I outline.

Therefore, If one uses my method, allowing the Audio Desk to blow dry the much cleaner lp is the better way. (This is my last step)

My method:

I apply cleaner
I steam both sides
I then use the VPI as another way of rinsing/extracting anything left on the lp
I then use the Audio Desk
I then set it ti dry further

Cheers!
