Projectors and replacement bulbs
I just checked on a replacement bulb for my spare projector (yes I have a spare projector) and I was pleasantly surprised to find that it was now half the cost it used to be. The reason I have a spare projector is because when I was originally looking for a replacement bulb (pre-emptively) the cost made it more worthwhile to consider a new projector (with higher resolution and brighter projection) than to get a replacement bulb. And honestly, having the spare projector has been very handy. I've used it at Con, lent to friends who needed something last minute ;), and so on. So now that the prices have come down I think it is time to buy a new bulb.
