The scope I use is a Tektronix TDS5104 and I've got to say it is rather good. Lots of automatic measurements, and it's quick too. Had one guy in the BEng year stealing parts off my project and even took my oscilloscope! He's struggling to get his working and rather than asking for help swapped it over with mine when I went for lunch. I had it working within ten seconds of returning so just carried on with what I was doing.
