About 8 months ago I was tossed between these two projectors and it came down to the cheapest price for me. I bought a refurbished HD33 and it has been flawless. They are both good entry level projectors and each have there own flaws. Epson has a great warranty and great customer service but a lot of people need it as they have convergence problems, loud iris, ghosting in 3D and dust blobs and you might have to return a few to get a good one. Some HD33 have uniform focus issues and you might be RBE sensitive. For 3D they are known to be one of the best. For my money right now the new Ben Q 1070 sounds like a real winner and out preforms both of these projectors with a lower street price but its new and who knows what might crop up. For glasses the HD33 has the most options as it will work with from cheap DLP link ($20) to expensive optomas RF and will even work with IR as it has a universal emitter port. Tough choice but I am happy with my HD33 and plan to keep it until maybe 4K gets reasonable.
