I bought my B3030 because of the hassle of the old plow truck that took
forever to warm up,and wouldn't be without one.
That said however,I'd probably not spend an additional $4500 to get one
after i bought one without.I almost bought one of those "cabs" for my Honda quad an add an electric heater but figured the excersise in futility trying to plow 18 inches of snow with a short 50 inch plow was an excersise in futility.
I'm thinking a guy could do a whole bunch of fabrication with some resonable amount of material and make up something at least as good as a soft cab a whole lot cheaper.I've seen them made from 2x4's even that worked pretty good,and you could always talk to a muffler shop that has a bender and be
amazed at what the could fab up frame wise,and the could weld it up too if a
person didn't have their own welder etc.
I'm just sayin..;-)
