Good morning, I've been looking at scopes on ebay and was wondering if anyone on the reflector has a recommendation on which ones to consider. My K2 is working fine but would like to look at the output waveforms and also use it to cleanup an old Drake 2C audio distortion problem. My first inclinations was a Heathkit 4540,4550 or 4560 and price is an issue as usual. Thanks Roy Vickers KF5YU
