the thing about structure is that people generally get it all wrong when it comes to what a "good" structure is. So many people like to get caught up in how many starting chips there are....while a big starting stack is nice for the first hour or so...it generally means very little in the late stages of the tournament. And where is all the money in a tournament? at the final table...generally the top three places. This is my biggest complaint about the tournies up the hill.....no play at all late, you can be chip leader at the final table and not even have 25BB so skill pretty much goes out the window. If the would just shorten the starting stacks by say 25% or so, and add in about 2-3 levels in the middle to late stages, these tournaments would be a whole lot better, and from the casino's perspective, take about the same amount of time.
Also check out the rake, it can be as high as 25%, and then they expect you to tip the dealers on top of that?

Not saying they can't be fun....just know what you are getting into before you plop down your buy-in.
Personally I think you will find better value playing the 1-2-100 cash games.
