FYI, one of the other methods to come close to zero-g is for it to happen like they did for filming Apollo 13 - by using a modified jet. I think the manuever is called a hyperbolic dive but zero-g's are achieved for short periods of time.

It's called the "Vomit comet" and I believe it generates microgravity for mere 30-45 second spurts at a time. KC-135 is what I think the model number was, and tourist flights on it sell for under $10,000.
