I have been using my Davis DL 450 for the last 3 years or so and I have about 1980 hours on it´s first bulb. So far my projector has worked almoust flawlessly but now I´m itching to replace it with a newer unit BUT only if I can seen a really BIG improvement over my Davis in picture quality in a BIG screen - mine is about 270 cm x 203 cm white matte. B.t.w. I watch mainly PAL DVD´s from my DVD-player - could, however, to upgrage it to a HTPC or a HVI-DVD-player if that is necessary. I´m willing to spend about 5.000 - 6.000 euros ( about the same in USD) for the new unit. I Finland it would mean f.ex. either HT1000 or H76. Would I get the really BIG improvement I´m looking for in this pricecathegory or should I stick with my Davis for another year or so.
