I think it would work, if you found a piece of 5/16” or 3/8” (or heavier) steel plate to cover the top.
I wouldn’t pay $50 for it, although you couldn’t build it for that unless you had a good source of cheap material.
Looks sturdier than some of the imported tables being sold as welding tables.
That said, I have one of the cheap folding imported welding tables in our small Az garage. It serves the purpose to a point, ie holds the material off the floor and provides a clamping surface for the ground. It folds up so it hugs the wall when put away, but is too light and flimsy to pound on. Given the space constraints, it’s the only option there.
At my Mi shop I’m making do with an auction find shop built table with a 1/2” thick base that looks like it is a cutoff from some other project, a heavy wall 6” pipe as a leg, and a 2+ foot square 3/8” steel plate top. It’s heavy enough to pound on and the base being round (like a manhole cover) makes it portable. Well worth the $6 I paid an an auction.
I have everything I need to make a bigger rolling table using the frame from the shipping rack my four post lifts came in, except the time / priority.
I say throw a lowball offer. It will get you started and is better than sawhorses and Hardiboard.
