Upgrade small oscilloscope to?

I have a FNIRSI DSO-TC4. Cheap ($65, includes component tester and signal generator), works for what I need it to do. But the screen is tiny, and my eyes are old.

What are recommendations on upgrading? I at least need a larger screen.

Is dual-trace something that people here use? Important enough to make sure I get a dual-trace?

Any other features you can't live without?

What price range do I need to be in?
 
For audio work, you don't need anything fancy
I would get a dual trace. Sometimes you may want to monitor 2 points(in and out, ore and post clipping, etc). DSO can be nice for documenting but not strictly necessary.
For something easy to use, look at some of the older tektronix tbs1062 and like models. I would avoid older CRT scopes like the 465. Yeah, they looks cool but they're not worth the hassle. They gobble up power, take up a ton of scape and are heavy. Many have components that have drifted out of spec, and while you can repair them, who wante to.
I actually just replaced my 485 with a cheap hantek.
Other features that can be nice is FFT or spectrum analysis in the audio frequency range.

Which model Hantek?
 
get something like a picoscope 2000 and use your computer monitor/screen. Cheap, easy to store and has a built in siggen. They are not great for doing detailed THD measurements, but any scope that is will cost $$$$$

Analog Discovery 2 or 3 is the way to go for this. Waveforms is pretty capable. 5HD, spectrum analysis and a whole lot more. There's also an audio analysis suite made by a third party. It's not publicly available anymore but...
I'm still only scratching the surface but if you want a PC scope with more tools, the AD is the way.
You can scoop up AD2s pretty cheap on eBay, especially at the end of the spring semester.
