Whatever you buy, there will be something at half the cost and twice the performance a week later.
I had a 7" CRT and scaler for about 7 years untill I moved that originally cost about the same as the D-ILA HD2K I bought 7 months ago (more if you adjust for inflation).
The alternative I might have been tempted by was the Infocus 777 which looked really good at the time but cost �20k. Better contrast, brighter, lower rez (720p), slightly pixelated, transition between tones a little more abrupt, but still a better picture than I had seen on other dlps up to that point. I may also have been swayed by that sleek black case design that looked as if it had escaped from Area 51. That price has since been slashed in half, so it just goes to show...
Back to your question. Very sharp, very smooth, no banding, no screen door effect, not the last word in contrast (but not substantially worse than my old crt), and the fan could be quieter. It should see me through the next decade.
Caveat: I have yet to get it to work with the G98 over HDMI so I run it component to the scaler, but to be honest the picture is still satisfyingly beautiful enough that I don't grumble too much. Works fine over HDMI with my el cheapo Toshiba and Panasonic DVD players, so I know where the fault lies.
