Logical Next Step

I presently have a Benq PB6200. I am generally happy with it. But, like a lot of people in this forum, I always have my eye on that next step. The problem is I don't know what that next step should be. I have never seen a rainbow, so I'm fine in the DLP world. Is the image quality of the SP4805 that much superior to the 6200 that it would be worth the reduction in resolution? Do I just sit tight and wait for the 720P DLPs to fall under $2000?


BTW, I'm watching DVDs about 90% of the time and HD the rest of the time. I have a Zenith upconverting DVB318 DVD player. My seating is at least 1.5 x screen width.


I really enjoy this forum and look forward to hearing some opinions.
