I don't belong to one for two reasons: Definite stage fright, and I'm busy and likely wouldn't make the time to go there regularly. So I built one for myself at our ranch. Thanks to the poor economy, I was able to pick up machines and equipment from failed gyms around the county, and I wound up with top-of-the line Cybex, Icarian, and other high-end equipment at pennies on the dollar. I got a $4000 smith machine that had been in a fire for $100, and I replaced the bearings, stripped and painted it, and it's good as new. I also got a complete $3000 racked set of hex dumbells (5 lbs through 120 lbs pairs) from a bankrupt gym for $500. I've been lifting since I was 17, and am still very active in bodybuilding.
