I think youve put this very well, about the true value of the "bells and whistles" vs what can easily be accomplished without. I find that often a bell or whistle that is nice to have, ends up being in the way in some fashion during the many instances that you dont need it. When I built my horizontal splitter I placed the top rail at about 24" knowing that changing the height up or down acouple inches would be easy. Turns out 24" works pretty darn good, allowing the height of small pieces added to reach my fingertips to be steadied while splitting, and still being low enuf to use a ramp of reasonable steepness for big pieces. I would certainly like to have vertical capability, but in sizing the H/Vs up I am not satisfied with the work station height and position provided in the horizontal setup. Certain ergonomic trade offs are made in allowing both positions, and they impact mainly on convenient horizontal use. Vert option would be nice, but its not very hard to get around the need for it if youve got a tractor/loader.
