Have you already considered and ruled out the Huappauge HVR-1300?

This card has onboard DVB-T and hardware MPEG-2 analog capture, so
unless you are seriously thinking of using satellite in the future, it
may be a less expensive alternative. One other thing to bear mind is
that the HVR-4000 (and possibly the -1300 with its analog and DVB-T)
has mutually exclusive digital tuners, so that it can't simultaneously
record DVB-T and DVB-S/S2.
