[I ordered the 72" version of the root grapple today]
I picked up the 72" grapple today, it looks to be worth what I paid, although you can tell that the grapple is hand made with hand cut steel because you can see some inconsistencies where a few individual pieces of steel do not line up perfectly and a few pieces of steel are not cut exactly the same size. The photo used in the ebay ad is probably a photo of someone's best effort in making this grapple because my unit is not quite as pretty as the one in the photo. However, overall the unit appears to be well made. I am not sure what type of steel is used but the grapple is fairly heavy, and the hydraulic cylinder and hoses appear to be of good quality. I would estimate the weight to be around 500-600 pounds. I don't know if I would want to rely on this grapple to make my living, but it will probably fulfill my needs and the needs of most land owners who are clearing brush and trees from their property. Considering that this unit is priced about 1k less than the grapple my dealer was trying to sell me, I think it is a fairly good deal.
