Perhaps this is an isolated incident, but I would have to recommend against Epson refurbished products. A few pages earlier, I wrote of my experience, but I'll give you the quick and dirty.
I purchased a brand new Epson 8500UB, returned it due to problems, and they sent me a refurbished unit. First, the top of the projector was filled with hairline scratches... I mean, all over. It looked like someone had sandblasted the thing.
Since the projector was going to be shelf mounted, the aesthetic scratches didn't concern me. What did was the thousands of scratches on the lens. It looked like someone had rubbed it with a rough piece of denim. Considering that Epson let this slip through QA concerns me.
With something like a projector, I'd personally stay away from refurbished... It's such a complicated, delicate piece of equipment, there are a number of things that can result from improper care. But again, that's just me. I'm sure not everyone has had comparable experiences.
Now, the flip side of the coin is Epson support. When I received the projector in poor condition, they jumped at the chance to resolve the problem. And, if the refurbished unit comes with a 2-year warranty, it may be worth it. But again, just my $.02 based on a recent experience.
