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.
