Gary, About a month ago I bought a Tektronix 475A Oscilloscope that Dale is talking about, on eBay. It cost me $252.45 including shipping. That thing is heavy and kind of beat up, but works very well - it's a 200Mhz scope with two channels and a multimeter. Once you compare it to RadioShack's 50Mhz scope for $800, I think you would agree that it is an awesome deal. I think you can get by without an oscilloscope, but when your circuit doesn't work, it simplifies troubleshooting by letting you "see" what's going on. Logic probe can't do it for you. Bottom line is, if you spend a lot of time dealing with circuits and don't care about the instrument's appearance, I would go ahead and buy a used scope. Works just as good (perhaps even better) as a new one, but doesn't cost as much.
