Well, I had a shop owner try to sell me MMATS Pro 641 for $600.00 AFTER I told him that I was interested in the MUCH more expensive Morel Elates ($1,500.00) that he also sells. (How often does THAT happen?) His words were "they should charge twice as much for these things".
I have never heard them and likely never will becasue MMATS is most active in the Southeast and very rare out here on the left coast.
Here is a link to an online retailer that sells them under $500.00:

And here is a link to the manufacturer's web site:

I went to the dealer locator on there and was so screwed up in Firefox (their web site kinda sux) so I took the liberty of copying/pasting the dealer info for Virginia to clean it up...
