My dad and I have been using a 25 ton MTD Yard Machine for 20 years now. It has easily seen 100 cords through it and other than replacing some bolts on the wedge carrier and an oil filter here and there, it has worked pretty good. Yes, there are a knotty piece here and there that it struggles with, but we easily go through 36" oak and locust without a problem. We have split oak up to 60" wide. I run a Stihl 261 with an 18" bar and a Stihl 660 with a 25" bar and the splitter has pretty much handled whatever we can throw at it.
With that said, I will probably end up buying a Rugged Split Type II in the next month or so. My cheap self is still trying to break down and spend the $3,000 while the MTD is still working just fine. Only thing really holding me back is the fact that I have some firearms expenses planned in the near future too and those will take precedence since the ATF is thinking about changing the NFA trust regulations. The main reason for the Rugged Split is the log lift on it. Yes, my dad and I can split 60" rounds on the MTD, but it is a heck of a lot of work putting that splitter in the vertical position and maneuvering the round under the splitting plate. Hoping that a log lift will make life much, much easier. Will still have the MTD for the small jobs.

Not too sure about the Lifan engine, but I e-mailed Ruggedmade about the compatibility of a Honda engine with the splitter and the bolt pattern they sent me allows a Honda to be used at a later date should I wish to do so. I was going to build a splitter like the Type II, but just the components themselves would have cost me more than this splitter costs. Only other concern was that it would only take 11 gallons of hydraulic fluid and there is no external reservoir, but again the Ruggedmade rep assured me that the way the splitter is designed with baffles in the reservoir, it would work just fine. Plus, the MTD and other lower end splitters have the same type of axle reservoir.
I really wanted something like the Timberwolf TW-6, but at $10,000 for that splitter, that was just not an option for the 10 or so cords of wood a year my dad and I are processing nowadays. Only way I could justify the Timberwolf is if I started selling firewood for a living, and I do something else for a living that will not justify the sale of firewood for a living unless I wanted to go big time on firewood sales. Plus, if the Ruggedmade gives me any trouble, I will just use the beam and parts from it to build something like the TW-6 with an exterior 20+ gallon reservoir and an axle with a suspension on it.
Only real downside is that there aren't many reviews about the Ruggedmade. The ones I have found have mostly been positive, with one bad review in several places by the same person, regarding the Type I.
