The Tek 935 that you have is a perfectly decent scope for vintage work. It can do just about anything you're likely to need and do it well. Forget about the old valve scopes, they are for testgear enthusiasts.
As Trevor says, learn how to use your Tek 935 and it will be an extension to your hands and brain. A DSO is a distraction for what you are doing.
I need a DSO for some of my work. My Rigol 1054Z does a pretty good job at what for professional users is a dirt cheap price, c£300. I'm still happier with an analogue scope. The fact you've got a knob for each function; the very direct relationship between what you do and what happens on screen; the way you get to know its foibles inside out after a while. For those of us who do a lot of TV stuff it takes a very good (= expensive) DSO to display a video waveform with anything like the fidelity of analogue. My DSO isn't in that class. But when I'm looking at a few nanoseconds worth of waveform that happens only once in over 100ms, or one shot happenings in complex logic then I can't work without a DSO.
