I use the Tektronix 2465 which is a fantastic scope.
*BUT* it contains digital electronics (no signal processing though) and mine has now lost some bits from the ROMs so has to be started using the "override" to the error that is flagged, at which point I find a bit or two missing from the on-screen characters.
Before that I had Tektronix's amost 100MHz lightweight portable
, the 585A
This was a great scope too and no problems fixing it. Nothing digital and all very spread out for easy access. But you had to be careful to use the correct funny solder and lifting gear helps.
The main snag was that in summer you risked problems from sweat dripping into things, but in winter it doubles as a fan-heater
