64 bit dvb-c cards

I have just upgraded my PC and OS (W7 64 bit) and found that my old faithful TT C2100 card has no 64 bit drivers so it is time for a change.

I see a TT C-1501 has 64 bit drivers and will do HD so that is an option but what do you guys think? Care to share the wisdom :) ...........

Thanks All.
