I had the use of the 37 ton Rugged Split for the last year or so, it was my brother's and he recently sold it. It had the electric start engine, log lift, slip on 4 way wedge, out feed table and adjustable stop for the return stroke. Pros: very heavily built, electric start was nice, log lift is very useful for large rounds and to stage smaller rounds. The out feed table allowed the splinters to fall out (witch it did seem to make more splinters with the 4 way wedge, but I collect them for kindling). 4 way wedge slips on and off easily. I was really impressed with the splitting power. Cons: very heavy so it is harder to move around the splitting area, in my hilly backyard I would have had trouble moving it without my Kubota BX. The out feed table is a few inches lower then the splitting beam. Not usually an issue but with the really large rounds it made it harder to move a split piece back to the beam.
Overall I thought it was really good value for the money.
