Thanks for the additional suggestion.
I ended up going with a Panasonic HDC-HS80 due to cost only ... The results were fantastic streaming in HD.

Few glitches with the broadcaster, but in general it worked pretty well. I managed to record live in HD for 5 days ... still a ways to go with the broadcaster but we were happy in the end.
