Brave makes/owns Iron and Oak. Built better than many other brands but priced accordingly as you have noticed. Brave makes a splitter down in that sub-1500 rang that I like. Check it out.

The Lowes/Troy-Built unit and all of it's MTD cousins, Yard Machine, Cub Cadet, etc. is a decent machine too. They had major issues in the past but I think they got all that straightened out. They look pretty but are very slow compared to the Tractor Supply Huskee/Speeco machines.
The Huskee/Speeco splitters are very popular here on this board and with good reason. 14 second cycle times (decent for a "cheap" splitter) and an engine that you can get parts for or replace inexpensively. Best bang for the buck is probably this machine.
Tonnage ratings are generally BS numbers created by the marketing dept to sell splitters. Compare cylinder diameter/length, pump psi, and pump gpm if you really want to examine the machine's capabilities. Doubtful that it will be easy to find all 3 numbers however. (especially pump psi)
Companies will build a machine (*cough* - MTD/Troy-Bilt - *cough*) with a cheaper, smaller, engine/pump combo but use a bigger diameter cylinder to up the tonnage rating. But what they don't tell you, or include in very small print, is that leaves you with a pitiful 19 second cycle time. I've not seen a single-wedge machine with over 20 tons of force fail to split even some real nasty wood.
One of the reasons I love Iron & Oak is the a la Carte engine selections. You could have a Briggs I/C, Briggs Vanguard, Subaru/Robin. or the Honda GX. Let your preference/budget decide. Electric start is/was even an option but is tough to find unless you special order. My machine is Robin-Subaru powered (EX27) and I love it. Was a few hundred less than the Honda GX and IMO runs just as well. I now have two of these engines (other one is on my pressure washer) and wouldn't mind having a few more.
