For $200 you should be able to find a good working 2 channel 100MHz analog scope or an older basic DSO. Key an eye on your local Craigslist; sometimes things show up there, but you'll need patience.
If you have any large universities near you, check them out and see if they have a surplus equipment store. Sometimes you might find test equipment if they refurb a lab or somebody gets a grant. That's pretty hit or miss, but sometimes you can score big.
See if you have any hamfests in your area. Ham swaps can be good places to get cheap older equipment.
Unless you get into cursors and measurement capabilities, analog scopes really didn't change much once you got to triggered sweep. A 1960's vintage Tek 454 has pretty much the same capabilities as an 80's 465. Everyone knows Tek, but HP made pretty good scopes in that period as well. There were many other manufacturers that made good scopes as well. For a while manufacturers made interesting hybrid scopes that were analog with some DSO capabilities. That was during the period of transition to pure DSOs. They generally had a higher bandwidth analog section coupled with a low bandwidth digital section (eg Tek 468). The DSO capabilities of those are poor compared to what's currently available and they were fairly complex animals, but they can be fun to play with. Avoid any kit scopes (Eico, Heithkit, etc). They're good for making clocks and not much else.
If you get an older analog scope, the odds are good that service manuals are available so if anything breaks you can fix it. In fact, I would not buy an older analog scope unless you could get a service manual. Manufacturers stopped providing service information, for the most part, around 2000, so an older DSO is likely to have little or no service information available. Even the factory serviced those by board swap. When those die, they become doorstops unless you're a very good troubleshooter.
An example of a older basic DSO is the HP 54603b. It's a 60 MHz scope, but usable to 100MHz, and has all the measurement and autoset capabilities. As a DSO it lacks storage and has poor glitch capture performance, so it compares poorly with a current Rigol, but it's an easy to use basic scope. You might be able to find one of those in your price range. It's a CRT based scope, so it's not quite as compact as a current LCD model, but it's not too bad.
The advantage of a new DSO (besides all of the neat features) is the warranty coverage. You can just use the scope and not worry about having to fix it if something goes wrong. Older scopes do break, but they can be surprisingly dependable. I have a 60's Tek 453 that I use occasionally and I've never had it opened. It's been on my bench for about 20 years now. That scope is pushing 50.
