I've always been curious about the 3325A vs. B -- there is more price spread between those two than just about any other HP A vs. B model. What's the difference between them, and is it worth anything like that much (obviously, Mike doesn't think so :-) ).
I've been happy with my A model, though it often fails amplitude calibration on powerup. Waiting a few seconds and then running the cal always works, though.
