Well, after looking ar $400K FFs, here's something on the other end of the spectrum.
Several years ago I built some very long ramps for when I had a toyhauler and even with motorcycle rims, getting the FC inside was a challenge of jacks, boards, and scrap lumber. Those ramps proved to be not strong enough for the job, and in cutting them up for other uses found that they nearly perfectly matched the heights I needed in between my scales, and the hillbilly platen was born. They were OSB boxes and weighed a ton, but worked for what I needed.
My new shop has a pretty level floor, and I decided to ditch the scale levelers. I made a water level and figured out how much distance was needed under each scale, and 3D printed spacers which I screwed to the bottom of the scales.
Then I needed a new platen because the old one was too tall for the much lower scales.
So, a sheet of plywood, a couple of 4x4s, a couple of 2x4's , and a 1x2 later I had gen 2 of the hillbilly platen. I might have a hundred bucks in it. It's much lighter than the previous. Hardest part was building a quickie router table so I could cut the blocks for the plywood. Old Rebco scales are almost exactly 3.5" high. The spine down the center of the underside needs to be planed off a bit.
Also on my previous one, I had sheets of metal to lay across the scales to make a ground plane reference for setting ride height. With the 3D printer, I can put a bar across the scales, measure the distance to the ground, and print a little platform I can use to rest the ride ht gauge on.
Also for those that have a dead head unit for their scales, I found this little gem on Amazon:

It only needs a power supply but it can also be interfaced with Raspberry Pis and Arduinos, which would allow you to make a wireless set out of your old wired ones for a fraction of the price of new ones.
