I can't answer your question BUT...
My dad once wanted some help at his mother in laws house. Wanted to rent a backhoe to dig some stumps/roots. I suggested he pay more and get an industrial machine.
He got a Terramite.
The job took two days on this machine. I am 90% sure I could have done it in half the time (if not even quicker) my own backhoe (JCB 1550-B)
BUT, an industrial machine was a couple hundred dollars more (he didn't factor in the father reach, speed and most importantly..... screws)
That darn little Terramite had...how to describe this... had a screw that held the wobble sticks down to their cylinder attachments.
What happens is when (on this machine) you push stick forward or pull back, all the force is really being applied and held by the screws.
About 1 1/2 days into this... one of the screws simply ripped out, stripping the attachment point.
I could think of about 3 ways they could have designed this better than they did.
It left the job unfinished and us almost unable to load the machine back onto its trailer.
It left a very bad taste in my mouth for how it's designed. I think your last comment described my immediate feelings pretty well.
