I'd never recommend a SS or fixie to someone who has never ridden one before as his/her only bike. It could be something you love, but then again, you may hate it. That being the case, I wouldn't recommend such a gamble. If you're interested in trying out a fixer gear bike, find an old garage sale bike or something off craigslist and convert it on the cheap. If you like it, then sink the money into a more expensive dedicated single-speed bike.
