What are the best LV NL holdem tournys for beginners?

[Player_X]

All,

My wife wants to play in a NL Holdem tournament in LV in mid-August. What are some good,(cheap), choices for her to play in?

How long do they usually last? What about ones that allow rebuy? What does it mean Add-on? What is the difference between buy-in and entry fee?

Any other advice would be welcome.

Thanks in Advance,
