Thank you upgrader, BrianMac, southpaw85, and JeremyR for getting specific about the 45! To me, detailed descriptions are usually more helpful than pix which often say more about the camera, room, lighting, angle, etc. than the PJ.
Of particular interest to me are the 45's black levels. All past and future comments on BL/contrast - including related info on screen and walls, ceiling, etc. near screen - much appreciated.
My situation: Very pleased with the sharpness, color, and motion handling of my current and first PJ, a DLP, the Vivitek H1186. But, of course, DLP black levels are more like gray levels. Would those of you who have had a DLP say that the 45 is pretty much the equal in all PQ departments except BL? JeremyR said something to the effect of the 45 is "almost as sharp" as the (DLP) HT2050. Surprised me. Would've thought sharper. Someone (southpaw85?) said 45 black levels better than Viewsonic which has an iris! That also surprised me, but the Viewsonic mentioned appears to be about six yrs old (looked on PJ Central)...so today's non-iris better than iris of recent past? IMO, posters comparisons to other PJs are gold. More, more!
I cancelled a pre-order for the 45 when news of the Epson 5040 surfaced. Like many, I'm still waiting for those initial 5040/4040 reviews. But, with all I'm reading, and considering the price gap, the Epsons will need really rave reviews to sway me away from my initial decision for the 45.
