It depends what your looking for. There are gyms in Vegas that can offer full MMA training like Xyience Training Center, Extreme Couture, or Fight Club. Those gyms are really expensive if you want the full package. Or you can focus on one disipline at a time and get better training ie. Striking or Grappling. For striking i would suggest Muy Thai at Master Toddy's (where I train) for grappling I would suggest Jui Jitsu at Mark Laiman's Cobra Kai. Both would be a bit cheaper.
I've trained at Xtreme Couture and it was a good time. Trainers really know what they are talking about and the gym is amazing. I definitely agree with Boondock, If you want to concentrate on other disciplines, which I highly recommend because you will get more out of it, I would go to some gyms that specialize. Cobra Kai is great for BJJ.
