This has got to be the easiest update I've done - mainly because all I had to do was buy the fan. I had absolutely nothing to do with wiring it in, so no tutorial here I'm afraid. Me and anything electrical is probably not a good combination. Luckily my father in law is super handy and had it installed in record time. Here's the good old before and after.
Before - fugly. Ok, so you can't really see much of the original fan, but you get the idea.
After - ooooh, swit swoo, that is one sleek looking fan.
