The 11pm daily tournament at Ceasars is around $100 and has great structure (40 min levels). If you want a cheaper re-buy tournament, off the strip at Tuscany they have daily (I think 10am) $22 buyin tournaments with rebuys and add-ons and all the money from RB and AO goes directly to prize pool. If you make some dough and want to try the higher priced buy-ins, Wynn and Bellagio are the best for structure.
Oh, and if you want Omaha games, Orleans (off the strip, get shuttle from Gold Coast on strip) is TOP NOTCH!
