Hi Hairyplane
I used to own the Millennium edition of the 800 really well set up partnered with a Lumagen HDP Processor which was fully ISF calibrated. I fed it DVD, Freeview and HD DVD/Blu ray which gave me a great HD image or so i thought

Don't get me wrong for SD from Dvd and Freeview it was really good but for HD material coming from a Blu ray there was something missing

Anyway i purchased JVCs HD 750 and the difference was staggering to say the least as i was now in HD heaven

I must also point out that my room is a Batcave style so no ambient light or reflections to bugger up the image. Once you see a fully ISF calibrated 750 which is a must to be honest compared to your 800 fully ISF calibrated then i think you'll understand what i'm talking about

Personally if it was me i would upgrade now to a JVC model if you have the funds either a 950 or if you can find a 750 then that will be even more of a bargain and forget the 800 for Blu ray

I'm just giving my honest opinion here as i owned the 800 as well so know exactly what image it can produce but if you really want a superb HD image then i would say go for a JVC model as i can guarentee you'll be truly amazed at the difference
