looking for dual tuner PCIe x1 for MythTV

so im looking for 1 or 2 PCIe tuner cards. currently i have a PVR-150, and it works great, and i know hauppauge has great support but i really dont know how support is for other brands. i really want something like a PVR-500, but i dont think they make one in PCIe. i currently only have SD cable access, but i wont turn my nose at some digital/HD stuff either (for the future). i have 2 free x1 slots and i would like to populate them with dual tuners if possible. i really like the Hauppauge HVR 1250 and the 1800, but from everything ive been reading, there isnt support for the analog tuners. so im wondering if there is anything thats similar that is supported.

picture/audio quality is #1 importance.

currently running Mythbuntu 8.04 64-bit.

Here is a current list. http://www.linuxtv.org/wiki/index.php/ATSC_PCIe_Cards

It's really limited and there is only one that supports any type of analog.
