Oscilloscopes are picked depending on what circuits (sorry cct's) you need to analyse..
I have quite a few.. for analogue circuits I use an old analogue teleequipment 15 mhz unit or a scopex 25mhz, for digital I have a digital tektronix TDS210 (I use it for analysing serial data, not interested in noise )
They all have there pro's and con's
Newer digital, colour, touchscreen.. look good, but they all do basically the same function... as far as I'm concerned bandwidth speed is the defining feature when getting one of these.
