I understand the desire to have the latest and greatest. On the other hand, the 811 is not very mature on the software side, and may have hardware design issues. So a delay may work out very well for you.
Got my 811 in December. 4 months later, STILL have junk dark images on all outputs, even DVI. If this does eventually get fixed in software, I will be a happy camper. But, given the timeline, 4 months to make the output brighter and it is still not there makes me more than suspicious that this is a hardware flaw and uncorrectable in software. Dish - prove me wrong!
EDIT - I also use a 301 and get great images from that, even though it is only SD and s-video, not HD and DVI. The 811 image quality is off the chart bad, but I admit that I am very particular about that.
