Hauppauge WinTV PVR 250 for FreeBSD 5.2

[Julian Elischer]

If I was building a little TV recorder, and 
wanted to use this driver, is thre a way of telling which Hauppauge
cards I can and can not buy?
Looking on their web page everything seems to be called "WinTV
something"
and model numbers seem to not be used very much...
