My first post in response: I just bought a single speed after 15 years of not riding my fancy road bike. It came set up fixed; I took a quick ride around the halls at work and immediately ordered a freewheel for it. It only cost about $8, and I can ride either way now, but I'm not going to: I don't feel the need for the life-threatening thrill of fixed, myself. You might consider that option: have both, and see which works better for you.
