IMO, the OP appears to be leaning toward a used Class C in the 30' range bought for cash.
With that said, I look at cost, condition, floor plan, build quality, and previous maintenance/repair history all about equally. Any major flaw in the previously mentioned is a DEAL BREAKER.
Most Class C MH's in the above range will offer roughly the same interior amenities so you have to decide if you want slides and jacks in your future. I like the Ford chassis but you have to decide which you prefer. (Ford, Chevrolet, other) You'll have to decide if you prefer going with a dealer or a private party and how far you are willing to travel to do the deal. What you want is out there if you are willing to look for it.
