in 2005 I was in vegas roughly 5 or 6 times and i loved the sahara tournament but i was back there not a month or two ago and they sped up the blinds, before it was the 7pm tournament which was decent and that was it, now they have a 7pm and 11pm tournament so they try to make sure the thing is sped up. However for the price it's one of the better tournaments but their cash games there suck, i think their highest limit is 4/8 limit.
Good tournaments are at caesars, good blinds but larger buy ins just 50-100 and one add on. The plaza has good tournaments but again 100 buy in usually with a single add on but the blinds rock, all other tournaments in town normally suck with fast blinds and small starting stacks they do the tournaments to get you there for the cash games. Only place that doesn't is Sahara but it's an ehh tournament but unfortunately probably the best for your money in vegas for the price.
