Last year I bought a 5' bucket from them for my SV100.
I don't normally do "cheap" options, they usually are very expensive when it comes to time and frustration. I don't recall the details, but when I called around elsewhere the buckets were decently to considerably more expensive and smaller in capacity than I wanted. I think it was the capacity that made me give JMA a whirl.
It is a ditching bucket, it's not heavily built, but it is built reasonably well. AFAIK it's not made of any special steel, I could bend/bow/smile the floor if I tried. I still dig with it on occasion I don't want a toothed bucket. It's also 5' of unsupported floor, most would have center support to help the floor/give material something to really stick to. Zero problems with any welds so far... the cutting edge bolts were too long by something less than an inch so I ground them flush with the nuts. I do wish it was bigger, but it was the best bigger bucket I could find.
I wouldn't mind it not being John Deere Green, but I haven't bothered to spray it another color either.
Looking up the easy to find details I paid $3227.48 delivered. Cat wanted $4251.44 and the struck capacity of JMA was similar to the heaped capacity. Not a meaningful difference in price, but
Here's a picture from last night, loaded out maybe around 250 yards.

Before I ground the bolts down.
Pumping driveway repair, excavate and backfill with 2-3".
