I'm still working on organizing ratchets, torque wrenches, drivers, extensions, etc. I have enough stuff for 4 drawers and paid about $650 for everything including tax and shipping. So the math maths above.
I think $160 per drawer is a really good estimate. Drawers are ~37"x20".
Just FYI, I don't know if they'll eventually go away, but I bought the large grids instead of the 6x6 16-packs. Was cheaper for me to go about it that way. Looks like the modular 6x6 boards will be the predominate thing going forward as those are being pushed everywhere in the marketing.
Oh and FWIW if this helps someone down the road, the "24 1/2in x 26 1/16in" boards are actually 23.5in x 25in (which is annoying because it fucked up my plans a little)...
