My needs are exactly the same.

So I'm willing to see any recommendations as a responses to your mail.

If any of you have any expirience with PC-based PCI/USB oscilloscopes which are
student-affordable, please share as well. Ideally, it would be a hardware being
able to measure signals up to 50-60Mhz.

I did however a bit of Googling and this was one of the most interesting 
devices:

Unfortunately, this product works only under Windows and the company's response
about any kind of support for POSIX-compliant systems was *very* strong "NO".
They claimed they have several clients working with their product under Wine and
VMWare.
