One thing I planned to do but didn't (yet) because I rigged up something even cheaper, was to just stick some pins and weld one bracket onto a gutted pallet jack frame for 3pt use, because broken pallet jacks are ~$50.
I don't think it would be any good for prying, but on a 3 pt unless you a hydraulic top link it'd be pretty hard to misuse the forks in that way like you can easily do with a FEL.

This without all the black parts.
What I ended up doing for LIGHT duty use was just use a U-shaped piece of c channel I was able to pick up out of a junk pile that is 3" c channels with one 4" c channel across the middle. It happened to fit just to the outside of the 3pt receiver hitch frame i already had. I used some tow hooks off a Jeep and made some sleeves over the thread of my 3pt lift pins so that I could back the hitch frame under the hooks and pick up the 'forks'.
The picture is in process of test fitting it on my small Case garden tractor (which is what i intended to use it on) but I do use it on my Kubota
b6100 as well. I have picked up a 5.6Lv8 engine on a pallet with it, and that's as much as i need to lift with it. The reason I built it the way i built it is so i don't have to pick it up by hand. I can back the tractor up to it to pick it up and put it down without getting off the seat.
Ive also used it on the bucket of the Kubota a couple of times, at which point it is like clamp on bucket forks that just aren't clamped.
