I have access to all current and past production models; TS160, TS360, DST3000, DST3100, DTC100, DTC200, DTC210, HDTivo, LG3200 / a, SR-HD400, SR-HD5, DSHD800. Sorry, not going to list all re-labeled LG, Metron, Philips, & Samsung models. If PQ is your #one concern you have my answer. If convenience is your requirement and are happy with simultaneous PQ, then you need look no further.
What surprised me is that the only labels that manuf their own product where Tivo, Samsung, Toshiba, & Philips. Then D* broadcast their D* exclusive label partnerships, and at the same time, RCA / Thompson did not announce, but chose Samsung to manuf their future receivers, followed by Samsung announcing they where out sourcing to Metron. Tivo still OEM, Philips who knows, and Toshiba told - good bye. Wondering why there are not many choices for Xmas?
If you look at the number of posts versus views, the DST has proven to be a relatively complaint free model, but, this is not a recommend. I keep saying it is not a receiver for everyone and yet it seems I am quoted on other forums, Gary recommended. Perhaps we should all agree that D* needs to eat their oats and re-evaluate their partnerships based on not so recent revelations.
