Those look very good, but look like Markham clones. I would advise a narrower grapple with only one upper claw. and I did not see that in their listing. Their prices seem a little higher than Markham. I feel a 48" is ideal for most applications, especially if you want to uproot and dig up trees, which is what I use mine for mostly. The narrower width (48") allows more focus of digging pressure, say when attacking a root ball. You can really concentrate the digging pressure rather than distributing it over a too wide area. And the narrow one is cheaper, lighter, and one upper claw holds debris in just fine. Once you clamp something with the upper claw, it's not going anywhere. As far as paint, the Markham is just spray painted, but who cares? Just like a bucket, there is not going to be any paint on the ""business end" anyway. Mine is a year old and has been used and abused and still looks fine.
My advice (if your tractor is a 45 horse or better) is to get quotes from both on a 48" with one claw, made from 1/2" steel with extra spacers in between the main teeth resulting in a 4.5" spacing. For a smaller tractor, go with the standard 3/8" steel. Markham made one like this for me and it has been awesome. Seems like it costs around $1400 last year if I remember correctly. This thing will really clear some land. I regularly push down 6" trees and dig up the roots. Hit them high to push them over and then push the teeth under the roots by driving forward and curl. Most will pop out. A wider grapple would not engage the root ball as well, as most root systems are only several feet wide. Sometimes for really stubborn roots, I use the corner of the grapple and only two or three teeth to concentrate the pressure. Thats my opinion after having used one extensively for a year.
