I bought a DLP online from a distributor of refurbished audio/video products. I love it. It’s great. Manufacturer-refurbished products can be much less expensive (like in this case), and you still get the same product, just not new. I do projection in a fairly large space in a fairly well-light environment, so I needed at least 1600 lumens.
