Several posters have mentioned what to check for. I recently purchased the Worksaver unit that has differential grappling capability with 2 pistons. The Worksaver is heavy duty and has welded, and replaceable, tines on the bottom for easily digging roots. I have managed to move some very big items including brush, timber, and boulders. With the heavy duty capability came a weighty unit which means watching the carrying weight vs lift. My JD 5325 with BH is a heavy unit which allows for the carry and lift consideration. The unit you show looks medium duty to me whereas the Long root rake + grappler looks to be heavier duty at the same price. The Worksaver as the single clamp or 2 clamp unit is more expensive but worth comparing. As others in this forum passed along to me the root rake - grappler is a fantastic attachment that expands your work capability. Good luck.
