I am looking for a good cheap projector that will help me in my ministry. I've realized that when you buy one, you are pretty much paying for the lamp alone. I found a cheap HP projector that takes an 180 watt p-vip lamp. HP sales them for 500 dollars. Dell has 180 watt p-vip lamps as well but for 300 dollars. Will a dell lamp work in a HP projector. I can't dell to answer this so any help would be great. Thanks
