I don't know why you are stuck with the sound card properties. But good news are
here: I've looked for national.com after your message and for only $10, i've
found adc08200 which is an 8 bit adc and has a 200 MSPS (mega samples per
second) sampling rate. $10 is very cheap so, we are not stuck with the 44khz
sound card.

I think, they've already done all the things that i'm gonna do in next 10 years
but this won't stop me ehe:-)

Heh, i don't think agents are going to like me.
