More home-theater projector questions. This time, it’s eBaytastic. Of course, there’s
I’ve read up on a number of AskMe threads on this subject, so it looks like I’m in the right place to clarify my further confusion on the subject.

I just found a number of exceptional deals for projectors on eBay from highly rated sellers. I’ve investigated them and found that the projectors are well received by critics and consumer reviews, so I’m good there. My questions stem from the fact that I’ve never owned a projector before: Namely, I’ve read that bulb replacement is a common thing and could potentially occur up to twice a year. How much does a bulb for one of these things cost, anyway?

I’m basically worried that I’m going to get a great deal on a good projector, have 6 months of fun with it, and then have to replace a bulb that costs 2 times as much as I paid for the projector (the auctions I’ve seen show decent units for under 200.00…at buyout pricing).

Finally, most of these units show no audio input. Should I expect to purchase a sound system of some sort to accompany these units, or will the units themselves project enough sound to be serviceable?

I need help with my out door guerilla cinema Idea. My thought was Laptop, projector, with bluetooth for sound. But I don’t know much about bluetooth headphones…
I want to sneak into places and hold guerilla cinema screenings. I thought bluetooth headsets would be a good way to distribute sound to a mass of punters with out having the sound attract attention to ourselves.

Seeing as bluetooth head sets for mobile phones seem to be a dime a dozen, I thought bluetooth stereo headsets would be cheap enough that the crowd could bring their own. But I’m yet to find ‘cheap’ bluetooth stereo headsets. Any idea’s on cheap headsets or another way to distrube the sound to punters in a quietish manner
