you get to enjoy all of the amentities of Summerlin without paying the premium, (ii) Summerlin proper, or (iii) way out the eastside pretty much where Sahara ends - there are a ton of great LDS families I know in that area, the schools are pretty good, lots of military/cops live out that way that keeps the rif raff down, and it puts you out of the valley pollution for the most part. Sahara with Hollywood area. I can link you up directly to talk with a few people I know up there that'd be more than happy to talk you through that area. Plus you can get a lot more home in that area than (i) or (ii).
My sister lives in Henderson and I'd call that area a distant fourth from what I've detailed. I lived in Vegas for two years and have visited that area a lot over the past 25 years.
