I found the answer to my own question. I know why they are not manufactured by all the big companies.....PRICE!!!

About 5 years ago, I got into a bunch of spaghetti elm that was just kicking my butt. I'd just gotten into scrounging my own wood and really had no idea what I was doing, other than the wood was "free". After hand splitting several truck loads and learning what words and doesn't work, an older neighbor from down the street stopped in to comment on my "new hobby". He offered to let me borrow his electric splitter that he was borrowing from a friend. I declined at first as I was really proud of how far I'd come from bouncing the first half dozen hits on each round in the first load, to learning to read the grain and age of each one with increasing success. After further consideration of my aching back however, I accepted his offer the following day "just for the really gnarly crotches"...
The splitter was a Ram Splitter (that are actually produced about 10 miles away from my house!) that struggled a bit at first, due to my using a cheap box store extension cord stretched to the corner of my yard. Another neighbor, who happens to be an electrician, wandered over to see what I was up to and brought along a heavy cord that required moving closer to the garage to connect it. WOW! We split everything we could find in the neighborhood and went and got another few loads while we had the splitter available. It took patience and learning how to work the grain, but it split everything and some of this wood was very gnarly and up to 36" across. A few of the rounds took both of us and my son to roll onto the splitter, but it split them all!
If I hadn't come across a good deal on an old gas powered splitter, I'd have saved up for the Ram Splitter. I still would prefer one, since I've never hauled my splitter anywhere else. I always thought the electric would be too limiting without a power source, but it hasn't come up yet. Maybe I should sell mine and upgrade?
Good luck if you break down and buy one!
