Yeah I've been looking for equipment for a few projects with rather wide bandwidth and frequency range requirements (not neccesarily oscilloscopes, but digitizer cards, waveform generators, etc.) and what I've found is that even if I could afford the equipment they dont sell to consumers. My best bet is going to buy some very old used things on Ebay, but in worried about software support. In some cases the software is so old I'm not sure if i could find it, or it's still exceedingly expensive.
