My advice is to buy a tux on the internet--there are a bunch of places, Discount Tuxedos , Cheap Tux, Fine Tuxedos, etc and you will be amazed to find that you can get one for about the same, or even *cheaper*than renting--the tux I got was a Neil Allyn, which is what you get when you rent, and came with a shirt, cummerbund, tie, studs, -- but you can get anything, including the Italian designer numbers, for much, much less than you would believe- they fit me over the phone(which, bizarre as it seems, was perfect--they need only sleeve length, chest size, and waist--you can get the pants finished at a dry cleaners for five or ten bucks.

The places that sell on the net are really uniform dealers, mostly in and around NYC--the jokes about looking like a waiter are true, a tux is really just a waiters black suit, and waiters don't pay men's store prices for them, why should you?

If you wonder why should you own rather than rent(other than that you pay the same whether you rent or buy)?Because next time someone wants you in a tux, you'll have one. The pants come with these little adjustment tabs so that they fit as well next year as this year--

When you have a tux you use it--I've MC'd several special events in it, and wore it when I was an extra in a movie--so the investment has been payed back several times over already, and it still looks great!

If it helps you any, think of it as a costume--
