Hi, just my experience i own a mansaver driver , a gas powered 2 stroke skidril, and a Rhino pd55. The mansaver is light weight, cheaper in comparison, and works okay but kinda cantankerous when going between soil types. It requires changing a weight that throws the valve and it’s the slowest of the powered drivers. The skidril drives t post like pushing them in butter but it’s kinda heavy and the Ignition switch vibrates to the off position unless you tape it up. Which stinks because then you have to pull it off the post to restart it. I’m planning on replacing the switches out with some stihl switches off a weedeater. The Rhino pd55 is heavy, requires a 80 cfm from a big hose but works awesome. If I just had one it would be the skidril despite their cheap switches. They say it drives up to 3 1/2” but that’s definitely not in our Oklahoma clay. I can drive a 2 7/8 pipe but it’s really working it and don’t forget your ear plugs. Good luck
