Gotta agree with Longsx3. Summerlin is top notch, Henderson is really nice too along with Green Valley. Beautiful homes in planned communities and low taxes and cost of living is still pretty reasonable. I looked to relocate to Vegas a few years back and did a ton of research.
Schools in Nevada are sort of a work in progress. They are good schools, very new and modern, but often lack quality teachers. It's a very transient society in the Vegas area with a lot of new people moving in and just about as many moving out each month.
If you really want to get away from the "Vegas feel" try Boulder City, where there is no gambling and I think might have restricted liquor sales, etc.
