This place is really nice compared to a Gold's Gym or some other lame no-name places I've been to.
This one at least has a pool (awesome) and has a great location. Even if you're just passing through, visit it for a free trial day.
But if you are serious about joining, they have killer offers at the start of each year. They let you sign up and get one month free for whatever the year is - (2007, $20.07; 2008, $20.08) so its a steal to get started.
The equipment is nice and so are the people - highly recommended.
