All depends on floor plan and budget. We ended buying an '05 Itasca SC 37B for $55k, but were very picky: W24 chassis, full body paint, low miles, all options and no rust. Another $5k for new tires and suspension upgrades.
Any bigger MH would require a DP, but it seems that floor plans are more limited than with gassers. (DW prefers a side entry to perching over the side of a cliff.) Gassers are definitely noisier, but the newer trannies have improved their performance up and down grades.
I wouldn't hesitate to buy one of the newer gas MHs unless I was planning to drive 20,000+ miles per year.
