Well, another related question for me is what registrar(s) to use - because I've lost the trust I used to have in my registrar, and when that happens one is left with little choice but to move.

Godaddy has lost the bad reputation it used to have, and their domain discount club has attractive prices.

I just bought a few names at moniker yesterday to test their system - they also get pretty well reviewed now, especially by people with lots of names. At least according to the google searches I've been doing on the subject. 8 bucks a name isn't bad. And they look to have a decent system for bulk transfers.

Name.com was mentioned as low cost - but didn't appear on lists of registrars that were well reviewed.
