What kind of tourney structure do you guys use?

I like a juicy tournament, and to get the rich fish into cash game mentality. To that end, I have unlimited rebuys for the first four rounds, when you're at starting stack or less (meaning you can do double-buys). After that, there's an add-on. It's glorious. Everyone has a couple of hours to warm up, then there's a reasonable prize worth fighting for.

Buyin - $20 for T2000
Rebuy - $20 for T2000
Addon - $20 for T3000

25 minute rounds

20/20
20/40
40/80
60/120

Rebuys end, addons bought.

20/100/200
40/200/400
60/300/600
80/400/800
100/600/1200
200/800/1600

At this point, rounds become 20 minutes. Gotta end at some point.

300/1000/2000
500/1500/3000
1000/2500/5000

...and so on. We rarely get past this level. With breaks and dinner and reseating and colorups and and all of that, it tends to take 6 1/2 hours to determine a winner, with most busing out after 3 or 4 hours. We tend to have 25 people, give or take.

I like the idea of a couple quickie turbo tournaments, but for my once-a-month affairs, I want it to be something special. This structure is nice because it boils the frog a little at a time, and before you know it, button soup.
