When planning a tournament, I generally make my own structures based on the time I'd like the tournament to last, the number of players and the chips in play.
I was looking to get a fresh perspective on tournament structures and came across pokersoup.com. They have a "Blind Structure Calculator" that I've used a couple of times. You can set up any type of tournament by typing in what you want out of the tournament and what you have for chips. It then spits out a structure sheet, and they even offer it to you in a printer friendly version.
It is very easy to use, so if you are holding a home game and want a professional structure, rather than "Double the blinds every 10 minutes" then check out the link below.
