I pay, effectively, a recurring fee for PyCharm. The personal license is €89 and comes with 1 year of upgrades. As they've been able to release upgrades after that year expired that looked interesting, I paid another €50 for it the next year support.

Personally I'm not keen on a recurring payment unless there's a clear benefit. For an editor, that'd be having a team committed to making it better. The JetBrain guys have shown good progress.
