Best registrar??

[nsood3]

I've registered a lot of names through 1and1 and bought some that wound up getting me a bulkregister account but its too hard to do things like update name servers at 1and1 and way too expensive at Bulkregister. What IYO is the best registrar to work with? The two cheif things for me are cost per year and the ability to update multiple domains at once.
