Thanks for the responses guys. The one thing I didn't mention is that the
Runco projector that was recommended has a proprietary video scaler built into it that does the HD upconversion, so the choice of upconversion capabilities from the receiver should be a moot point (assuming it is as good as the reviews say it is). If that is the case, it looks to just be a matter of choosing a receiver that has the right connectivity and features.
One of you guys asked about the reason the MC-1 is available used... the former owner upgraded to a newer Lexicon (~$6k), which is more than my dad wants to sink into this upgrade.
Thanks again for the advice.
