Once I get my projector, it will be used as my main tv. I'll watch tv and movies and play games on it. My question is about how long should I expect to get before the bulb needs to be replaced. I know it says like 3000 hours, but just curious in terms of like months, weeks days, whatever, you guys who use your projectors often are getting out of your bulbs. 300 bucks is steep for a light bulb and I would hate to have to replace it once a month. Also can u change it yourself? or does it have to be serviced???
