I switched the last of my domains over to name.com (already had one there). Bunch of the registrar's have discount codes at the moment to. (name.com's was "nodaddy")
There are several threads and responses today in all the GoDaddy threads all over HN with suggestions. Many of them pointing to namecheap, name.com, gandi.net, and a few others.
Would you mind adding any domains you're transferring away to this list? <a href="http://stopsopa.mattbearman.co.uk" rel="nofollow">http://stopsopa.mattbearman.co.uk</a>
I've used 'em all... I like GoDaddy, but their UX is very confusing. Name.com ( <a href="http://www.name.com" rel="nofollow">http://www.name.com</a> ) is my choice of late. No crap, easy UX, and they actually have an awesome DNS management tool.
