At 30 cord a year
The increased quality and speed will pay huge dividends in the long run. The American splitters are commercial grade machines designed and intended for use with a 4-way wedge and an outfeed table, both options that are invaluable for increased productivity. What model(s) in particular are you considering?
One feature I would recommend adding if you go with the American, is adding a second hitch to the motor / hydraulic end of the splitter. This set up allows you to hook up and move the splitter without having to move a pile of splits to get at the hitch on the wedge end of the machine. This was one feature, along with auto-cycle function, that made the decision to invest and upgrade my T'wolf TW-P1 to my current TW-2HD.
All splitters hold their value pretty well, but American splitters are highly valued in the used machine market meaning if you ever decide to upgrade, you won't take a big hit when selling it.
