The reason I bought 2 was 1 for me and 1 for a friend. Ok, time for a review after a good nights viewing.
Reason for buying: A few years ago I owned a Panasonic AE-2000 and an Epson TW2000. Both very good 1080p projectors (Costing about $4000 AU at the time) and the reason I sold was I moved into a unit and didn't like the UHP bulbs.
I make films in my spare time, and after completing my newest film I wanted to watch it on the "Big Screen", plus I have a huge Bluray collection which looks amazing on a big screen.
Currently I have a 65" VT Panasonic plasma as my main TV, but for years Ive missed the 90-100" picture for movies. So how does the K330 work out when I am used to HD projectors and have a decent main TV?
The good news is, I'm impressed. But let me begin by how the night started.
Initially I had a mixture of feelings. I was surprised how small and lightweight the unit is, and was impressed by how big and detailed the picture was. I started it up in the late afternoon, and the extra light made it too dim for me to use. I would not recommend this projector if lighting is used in the room.
With all the lights out in the evening it was great.The colours really popped, and brightness and contrast were both fine. The picture was very close to my memory of the AE2000 which is impressive, if anything I have been spoiled by my plasma's black levels and at first was a bit distracting.
At 90", the resolution definitely comes into play and I certainly look forward to a 1080P screen. That being said, when you go to the movies I'm used to non-HD, and honestly I wasn't too overly fussed by it, its still clear and sharp, and the slights loss of resolution almost adds to the film look. I tried shrinking down to 80" but preferred the bigger picture over a slight improvement of sharpness so I guess it isn't that bad.
The only big negative, and I stress is quite possibly the big deal breaker, is to decide of you are mounting on the roof or not. For me I can't, and it is really awkward to position the projector in an area that doesn't affect the seating arrangement.
For example at 90" the projector is back about 2.5mtrs, but that is literally right in front of my seat. If I move the seat back further I lose the benefit of the big screen look, and can't go closer as the 720P resolution starts to really be affected. I can live with the positioning, just be aware it is far from ideal. From memory my AE2000 had an optical zoom which helped greatly, but I understand you get what you pay for.
And that brings me to the big question, am I happy with it? Is it worth the money?
I think I can answer this very easily. I would much rather watch a movie on a 90" with this 720P LED projector than on my 65" 1080P Plasma. The benefit of having such a cinema like size and very good quality, vs the plasma which has an amazing picture but still feels like a TV makes the projector a winner to me. When you then add to the fact the projector cost $500 vs $4000 for my plasma, YES its worth the money.
If I was to only watch movies I would sell the plasma, but I much prefer it for TV and PS3.
Hope this helps, any questions happy to help, and if you are still contemplating to buy one, don't, you could be watching cinema in your home.
And if deciding which model to buy (The Acer/Viewsonic/LG/Optoma) I honestly could not see how any of them could be much better or worse and they should all be pretty much just as good. The biggest limitation of these projectors are they need 1080P, and an optical zoom, so until the new models come get on board and enjoy
