fihu I have! I set up an instance as a test for moving our main Hemispheric Views feed away from fireside.
Aspart of this test, I tried moving two others:
Since One Prime Plus has user management, I have not completed that migration yet, but SOON! 3x2 is fully migrated now and only only Castopod.
Overall I think it's super nice. It's a little quirky, but it's also not $10+ a month. I would say it's definitely worth a try, and really one of your only real solutions for turnkey.
