I had one of those and as you say it took a good 2-3 days to build it, deck it, paint it with sand paint, and get it road-ready. They are by any objective measure pieces of crap but like a Ural, there is a perverse satisfaction one gets out of using one, repairing its deficiencies, etc. it does fold up and store pretty compactly, and it can be customized and braced to shore up its weak points.
I ran mine up and back to Vermont with two dirt bikes on it dozens of times, then built stake sides for it and hauled all manner of brush and firewood and debris with it. Moved a few friends. Drug it around my lawn and woods behind my lawn tractor full of hay and children.
Finally gave it away after 6 years or so for a case of beer and it lived on hauling a bike around for another 4-5 years last I knew and by then it didn't owe anybody anything.
So if you're a little short on dough, don't mind fiddling a bit, and resourceful then I'd declare them a solid value.
