I have the SM-26e which is the electric start one. The biggest downside is I have to push it and roll logs by hand!!
No, I am pretty happy with it, when I bought mine they came with 19'2" bed rails so I can cut up to 16' lumber but I'm thinking they have gone to a shorter bed.. not sure though. They were getting them sourced from overseas like everyone else, but I think they are tooling up to make them all here in the US which is nice, but probably the reason for ordering delays.
My suggestions for whatever you get... Get a good sized motor with the electric start, it never runs all day and you dont want to be yanking the cord all day, get the auto lube system (big reason I got the
woodmaxx) and you want the push handle in a position that is easy to push, and get a bed long enough to cut usefull length lumber..
and good luck on your endever.
