I see a future member of the TEA group in the making
I also come from a country where buying test equipment is rather expensive, and there's not many options to acquire good gear without having to sell your organs to afford them.
My first scope was a Rigol DS1052E (which I still think is an amazing entry level scope -especially if you hack it to unlock 100 Mhz bandwidth-) that I bought 10 years ago, and I kinda burned all the money I had at the time on that purchase.
If you only want to see waveforms and do basic measurements, an analog scope is definitely an option (and I love them, they are beautiful things), but since you mentioned that you like working with precision and low-noise stuff, I guess it would be useful to you to be able to capture glitches, measure jitter, etc. With that in mind I think a digital scope would be a better option.
I normally would advice against handheld scopes for a "main" scope (they are fine as a secondary or "field" tool) because they usually have pretty awkward controls, lack features (limited triggering options, limited storage capabilities, poor measurement capabilities, barely meet specs, etc) BUT that Hantek scope you mentioned seems to be fairly decent on paper (I went through the manual and looks fine, BUT I'm yet to see a review showing if it meets its specs, and all the features actually work, though).
There's a recent review from Defpom on a budget scope that looked pretty promising:
That instrument seems to be exactly the same as the OWON SDS1102, which is available even here in my country at a reasonable price (still higher than its standard price, but definitely cheaper than the Rigol I purchased as my first scope) Maybe it's also something you can get where you live?
Aggressively stalking local auction sites is also recommended
. Hopefully the second hand market in your country is bigger than here, though. Apparently VERY few people in my country worked on electronics in the past couple of decades, so it takes a miracle to find good used instruments at decent prices.
