I bought a new bulb for my projector through ProVantage.
I swear to god the thing was on my doorstep before they even charged my debit card. It was regular shipping too, but fast as lightning.
As a result, I am impressed with these guys, and they have been around a long time, although I'd never heard of them before finding their site while searching for a replacement bulb.
Anyway, I ramble... $154.38 at ProVantage:
