You have to consider the fact that UNLV was fully ABA-approved in February 2003. I think it only has two graduated classes; so if there aren't many people working in other states, that may be why.
Although the school is fairly new, it is a good school. If you're moving to Vegas and you really want to go to law school, by all means, go for it. The price is very reasonable: $7,000 for in-state; $14 for out-of-state.
By the way, have you seen the facilities? They are AWESOME!
