I totally agree with you. When the HDNets were the only thing out...they cool. But Vooms programming has all of that covered. (The only thing I do miss from the HDNets is the show that shows all of the trailers in HD).
Sci-fi channel would take me over the top (that and TNT-HD).
Since our transition from cable to VOOM last month SciFi is the only channel that I miss. I agree that VOOM should prioritize more HD channels right now, but it would be great to see SciFi out there in the future.
