Has anyone had any experience with the UnderFlow sluice?

Hi Pat,
Not sure what to think of that mousetrap. I've watched his vids before and I'm sure it captures Gold well but holy crap on that pricing! Way out of my league for a hand sluice. Looks a little flashy and overbuilt.
Lately I've been using a $50 Angus MacKirk (mini long tom) while guiding at the ranch and I swear ta God... that little bugger does as well as any hand sluice I've used (including my A52 Gold Hog mod). I class down to 1/2" and scoop it on through. It cleans up LIGHTNING FAST and is light as a feather. I don't think Angus can be beat value-wise. I don't work for them or sell mining stuff. Just my experience.
Wish I could give you a review on that UnderFlow jobbie and sorry about pimping the Angus... but I'm not sure how anybody with common sense could justify that much coin for a hand sluice. I know, I know... reduced classifying time is a selling point for the UnderFlow but that little Angus will process fast with very minimal classification and leave ya with a much fatter wallet and probably just as much yeller.
Just my opinion, take it for what it's worth. The UnderFlow thingy might well be worth it, I don't know... it hasn't been on the market very long, it's still a puppy. "Gold Cube" seems to have caught on with the same concept, maybe that will too.
If ya spring for one I'd like to hear how well it works and if the material production increase is worth all that cash.

Funny this comes up right now, cause i've been looking at that design for a couple days now my self.
Being unemployed right now and all , I'm planning on building my sluice from whatever i can from around the house.
As i've been reading a lot of people keep saying that the gate adjustment is really "Touchy". maybe i'll have an opportunity to build and test this design over the winter.
