Forgive me for piling on yet-another-unsolicited-registrar-recommendation, but I'm a big fan of NFSN due to their terms of service and feel safe that none of my domains will ever get pulled without very good reason. I've never had that trust tested, but it's at least spelled out:
They haven't been easy to get a response from for me. Tried to ask a question that wasn't in the FAQ and got silence. That was a few years ago. Went elsewhere. Same situation different question last year and again no response. YMMV but I got zero mpg.
I've contacted them a few times over the years to set/change the glue records for my vanity NS and they were always very responsive. It also cost like a dollar each support instance, but I still haven't spent double-digits contacting support in over a decade of membership :)
