I concur. Gandi.net has excellent support, predictable pricing, and a reasonably good admin interface. Also, their email reminders (e.g. to renew a domain or verify information) are pretty much plain text and straight to the point, which is all I want.

I use gandi as well for all my domains (about 100). But ever since they switched to the new v5 platform. I've been getting very inconsistent problems. I had to migrate all the domains to the new platform, but every so often I find some domains that haven't been migrated. All on the same account with different handles, which makes it hard to find the ones that haven't been migrated
