Thanks for the pointers and a new post - never would have found the old one on my own.
How about the $400 version - a one-off made of CNC red (or green) anodized aluminum with laser etched white markings, sold in a red (or green) systainer with a suitable router bit - choice of 8mm or 1/2" shank and 3/4" or 20mm diameters, and all in fitted foam? I think someone is missing a marketing opportunity. And imagine how much you could charge for the 1/4" thick aluminum pegboard template, if you could figure out how to make it work technically.
Seriously, hoorah for the reasonable price. This just became my new first choice for how to make an MFT top if I ever need one. (My second choice would be to have it CNC'd.)
