I go to Network Solutions to look up stuff at their whois connection, but I do not use them. I used register.com earlier in my career, and stay away from them at all costs.
A friend subcontracts my current webhosting, which actually could give me 24/7 service if I needed it, which I have not. Since I know him, if something went wrong I can get to my house, if necessary, to work on any sort of problem.
