I wouldn't discount BRBs so quickly, as the humidity issues are fairly easy to deal with as long as you give them a nice moss hide and one or two bowls big enough to soak in.
I sold my adult BRB a *looong* time ago, but here he was, awesome snake and a very easy to manage size:
For a quality hog also check with Chad Duggin of Duggin Reptiles (http://www.cdreptiles.com/)
I got a lovely female from him a while back and he's a great guy that produces true locality hogs.
Hogs average 4-6' and are great little snakes although tend to be hissy posturing babies.
Here's an old photo of my adult male from Rio Bravo (sadly no longer in business).
Good luck with whatever you decide!
