In for a penny in for a pound ...
Thing is for me I'm lucky my projector is a business expense (we do multimedia stuff), so upgrading is not that painful for me.
However if we can get 4000:1 CR out of it at D65 that would be 4x better than now?
I'm reluctant to move to the sony cos they are quite a bit more expensive and I feel that I understand the Sanyo series, plus get a good trade price.
Personally all the LCD on the market are dissappointing for me.
I bought a Sony HS50 a short while ago and I'd set myself a strict budget of £1600. I also had to have a 720p machine, this limited me to LCD's.
There was nowhere to demo around here so I took a leap of faith and bought what the general concensus thought was the best and that was the HS50. Soon as I setup I was immediately dissapointed with the image, I'm not an expert but I do know when I see a good picture. The Sony was average at best. I stuck with it and did get a better picture by messing around but shortly afterwards the lamp died and I refused a replacement and asked for a refund.
To cut a long story short I decided I had to travel to actual see what was on offer and demoed a couple of DLP's. The first was an infocus 7210 and the second was a Mitsubishi HC2000. Both were a big leap over the HS50 much better colours and you didn't get that horrible iris thing making the picture way too dim. Everything was punchy all the time.
These of course are both WAY out of my price range (around £3500) but I decided to look at the second hand market for a DLP. Still looking but I couldn't live with an LCD.
