Price changes are a concern indeed. But I think if you get something form your country, or a .org, it should be mostly fine.
I've had the same .org domain for around 15 years now. Except for the coup we've seen last year where somebody tried to buy it privately (thankfully averted, I believe), I've see no price hike over time.
