Hallmark make some very nice campers, for sure, but you pay for it. What's the lead time? From my reading, they're a lot like FWC - in other words, plan on waiting a while.
For my money, the Northstar is hard to beat. There's even inventory that needs to be moved:

(I've been seriously considering upgrading to this one myself; we have a TC650 now and the girls would love a "bathroom")
