After reading a lot of posts on this forum, I ordered a Darbee about 5 weeks ago from Smarthome - picked it up on Friday and installed it.
It is great. I have it between my Denon 4308 and my Pioneer 151. Its a good addition to my system. i set it on HD 50% and all is well with no handshaking problems.
Thank you all for your input (it has the new software).
btw - try watching the blu-ray of Planet Earth with the Darbee on HD 50% - it is absolutely sensational.
