I have a Troy Built splitter that was $600 when we bought the house. Son of the owner had two of them, and offered it to us cheap. Used it for 3 years, it did the work, but was slow, has a 16 or 18 second cycle time. It was helpful to flip it vertically for big rounds. I split 5-6 cord or so of red oak, ash, and hard maple, and a couple cord of poplar for shoulder season wood.
Upgraded to a Wolfe Ridge 28 ton compact commercial splitter with auto cycle, log lift 4 way and 6 way wedges. More than you want to spend, but if time is important or limited it’s a game changer. I can split a cord an hour and not sweat. Cycle time is 6.5 seconds, I can set a round, hit the two levers, grab another round and drop it on and hit the levers again. Oversized red oak 30” plus dia, needing to be split 4 or more time slows production down a bit. I split 8 cord for us now (no oil bill anymore) and 4-5 cord to sell to friends.
