It sounds like you want fantastic 3D. In that case, DLP trumps all for home theater. I have an HD3300 and it doesn't have "minimal ghosting" or "almost non-existent ghosting". It has NONE at all. The image is so sharp and the "pop" you get is fantastic. You will never have to worry about dust blobs getting onto your lcd panels, you won't have to clean dust filters (DLP has a sealed light path), etc. You can buy DLP link glasses for cheap as chips if you know where to look also. The Epson will be brighter for 3d, but I'm projecting my HD3300 onto a 143" screen and it's plenty bright (you have full light control, so that's good). That said, I had a Benq W5000 and it crapped out after 2 years and I had a bad experience with their customer service. They essentially told me in not so many words that it would cost an exorbitant amount of money to fix and that it would be better to just get a new projector. Have you considered the Acer 9500BD? The HD33 is great, but it has limited flexibility in terms of placement (I really missed my lens shift from my W5000). Hope that helps.
One thing to note...not all glasses are alike. I have a pair of Optoma ZD201 DLP glasses and they are much, much better than the cheapies I own. They other ones are fine, and good for guests, but if you want the best out of your projector, the ZD201s are the best. Of course, this is IMHO, and you will get naysayers, but meh.
