don't buy a fixie if you're not comfortable using a fixed gear in busy traffic - you'll have too many issues. you may be better off with a singlespeed where you can freewheel - and fit it with a flip-flop hub so you can used it fixed as needs be.
there are loads of good fixed/SS bikes out there - Spesh Langster, Planet-X, Charge etc. or get an old frame and build it yourself as it's easy enough - that's what I did with an old frame of mine. resprayed it and then built up with a mix of 2nd hand and new parts.
they're good fun for pootling around on in winter and easier to maintain
