By the way: Some time ago I made a very cheap A/D converter (components
cost cca. 50 EUR) that used a modified ethernet adapter on PCI bus. It
had maximum 10MHz sampling frequency (TDA8703 IC)

I had some problems with reliability of the FIFO buffer but I believe
that would be simple so to solve. Maybe you could make something out of it.

I later lost interest in software radio and didn't bother to develop
this further.
