I just received a USB/PC-based oscilloscope that I ordered from (persona non grata). I know it's not going to be as good as the real thing but it will help me analyze an occasional signal and take some measurements. Now I've just got to figure out how to use the thing. I don't have any experience with real oscilloscopes so this semi-simulated one is making a lot of assumptions that I know what I'm doing when in fact I don't 
I'll figure it out eventually. It's going to be a fun little toy.
