[mythtvnz] Satellite tuner recommendations please

[Austin Green]

Hi All,

I currently have two TeVii S421 DVB-S tuner cards, which suffer
from a couple of problems:
(1) They seem to be not very sensitive, in that my Freeview box
can tune all stations with no trouble, but the cards are a bit
iffy on some channels.
(2) They are supposed to work with the 3.13 kernel under Trisquel,
an Ubuntu-derived Linux distro, but they don't.  They work on the
same hardware under Debian Wheezy, using the Liplianin drivers and
an older kernel (3.2, I think).

I would like to know if anyone can recommend anything better.
Need something that:
* Works with stock 3.13 kernel
* Is reasonably sensitive
* Available in NZ
* Not too outrageously expensive

Cheers,
Austin.
