I've been looking for a log splitter too, and saw a couple of Americans in New York a week or two ago. They look to be top quality, and have moved up to the top of my list. The AM-24H is too low to the ground for me (basic price was $1700). It is "horizontal" only, not sure I would like the way it shoves the splits off the end - no way to catch them until you add a shelf. Then you would have to unhook it from the tow vehicle, just extra messing around. I am interested in the Am-24V which does horizontal and vertical (price was $2100). I would use it mostly horizontal, and the wedge is on the ram so the splits are not shoved off the end and go vertical for the really big chunks. (It is probably what you get used to....)
What impressed me was: 1) the "lay out" - how things are out of the way. Many of the box store brands are obviously make compact to save on material and everything gets squeezed together. 2) The hydraulic hoses were bigger and higher quality than others I have looked at. 3) massive plate at the end of the beam- what is that, 2 inches thick??! 4) overall "solid" build on everything.
The AM25S has the heavier beam than the 34 series, so it must be incredible! I searched through this site and others, and found many, many happy users. I don't think you could go wrong.
