This is the rest I just bought a month ago. It was on sale for $22.95 I think it was. Once you get used to it (and it does take some getting used to) the rest actually works real good. Also it is light weight and easy to move around. With the front ramp extended out, it will stand in a corner on its own and takes up little to no space. The thing you need to learn to work around is the handle on the back of it.
Also I would think that the one you pointed out would work real well also. I do not even sand bag this one. I figure I can absord the recoil of the rifle like always.
