If you can afford a mid-range scope, buy it, by all means! It will aid your understanding of basic electronic concepts unbelievably (eg. what happens when I increase the resistance in this high pass RC filter?; is my low pass filter time constant right to get smooth out my PWM waveform etc.). Although I work without my 'scope most of the time, every now and then I feel blind without it (am I loading the output of this opamp too much?? - can't see using my multimeter, plug in the scope). It helps tremendously in getting a 'feel' for electronics. What to go for: I am a bit apprehensive about the PC based ones, since most of them are fairly slow. I would recomment going for a mid-range analogue 'scope, although I can't name any brands (can anyone else help?). I you want a cheeper option, you could make a PIC project out of it - I have seen a number of designs interfacing the PIC16C71 to the PC via the parallel port - have a look around. It may be the solution until you have a better idea of what you want. Cheers Roland
