I need free primary and secondary domain servers. So far Register.com is good cause they are so easy to use but $35 per domain is not cheap.

try stargate.com.

You use them yourself? Do you like them? I used directnic once and they suck. I had not idea on how to configure it.

I use them and like their services. :)

I use Directnic. Nameservers are free there. But the actual DNS going through them is $5 a year.

namecheap is good. Got my domain names from them.
Great control panel and of coz ... cheap rate

Why would anyone want a company like register.com?

mydns.com provide free name servers...
