I've been going to Sumits Biltmore for over a month now and LOVE it. The studio is clean, gorgeous and always smells nice (not like bikram, how the carpet combined with everyone's sweat can make for a not so amazing odor).
It seems to be a much better workout than doing bikram, as it incorporates those poses, in addition to a power flow. The music is also a HUGE help, especially at those 5:30 a.m. classes, when you need a boost to get moving in the morning.
Would highly recommend it and for those just starting out, it's only $20 for 2 weeks so you can't beat that. I signed up for monthly unlimited, which also ended up being cheaper than the bikram studio I was at prior. Great place and I'd definitely check out Kim's classes - she's a great instructor!
