Hi there... I ended up (as I think you may know) taking a punt on the TeVii S470 PCIe DVB-S2 card off TradeMe. I am REALLY happy with my choice as it installed easily into Windows 7 64bit and seems to work really well.
The other card I was contemplating was the AVerTV Satellite Trinity TV Tunerbut this was a lot more expensive and contained other inputs that I didn't want/need.
I did also look seriously at the Pinnacle dual tuner DVB-S card, but it appears to me that these are now a legacy card and are no longer supported.
Ultimately I will wait for the Black Gold as I think it will be a better card, but I am happy with the TeVii in the mean time.
Are you using the TeVii with other tuner cards? Basically I am considering buying one as I'd really like 2 DVB-S tuners in my system (preferably 3 but that can wait :-) ).
