Depends on how much you download. You can pay a once-off payment for a block of data and it lasts indefinitely. I’ve got a 5TB block I’ve had for over 10 years. I think it was maybe $25 when I got it?
Edit: If you need more data, there’s plans with unlimited data for a few dollars per month.
I like the default one in KDE (Spectacle). It does everything I need, and can take both screenshots and recordings. I don’t think it works with other DEs though.
