I don't have much to say about replacement lamps. I tend to buy branded original lamps, but a ton of people have had good luck with OEM lamps, and others have had terrible luck in general. So..... I just have very little to offer on this matter.
I think maybe if you are trying to stay on a strict budget, that I would be looking at a original replacement bulb only and would swap the bulb itself instead of the entire lamp and be super careful. But, I would still lean towards trying to get a proper factory lamp if I could.
