Well these days 400 to 500cc bikes are considered mid sized due to the advent of 650 and 700cc bigbores with some 800cc models slated for release in just a few months. As far as 1 brand being junk or another being absolutely trouble free, it just ain't that way any more. A lot of guys get brand loyal which I guess makes them feel better about what they themselves bought and want to bash everything else. Just gotta read between the lines and decide for yourself.
I always tell people to check out their local dealers, especially their parts dept. to make sure they have parts available. It doesn't matter what you buy you're gonna break something some day and you don't want to park the thing for 2 months waiting for parts. Talk to the guys who ride where you live and see what they're riding. This is one time you're not better off being different. For example; around here Arctic Cat is a no-no for the simple reason there isn't a dealer within 100 miles.
As far as being competitively priced goes, they're all competitive all right! They're all competing to see who can charge the most! 329cc Honda Rancher, 290cc Kawasaki Bayou, 362cc Kawasaki Prairie, 376cc Suzuki Eiger, and all the rest in this size range have a suggested retail that is within pocket change of 5 grand one way or the other. The bigbores are only 2 grand more for a whole lot more bike.
By the way, East Tenn. where you're from has some of the most beautiful countryside to ride through and hunt in ever was. Best of luck with your choice.
