RegisterFREE.com will do registrar transfers for $12. This includes the mandatory 1-year renewal. Get away from NSI and renew all your domains for $12 each!

I started using RegisterFree because, as great as Joker.com is, they're not as accessible in case of a lawsuit-- Joker is in Germany, RegisterFree is in New York. Not sure if that's sound reasoning, but it's peace of mind. Both are inexpensive and have fast purchasing service (two days to activation, usually). The real test will be when I try to transfer ownership of a domain.
