Best reseller for a domain name

Looking to purchase a domain name separately from the package (using SliceHost and want a domain name) and I was wondering what is the best reseller to purchase from.

All the pricing for a yearly renewal is under $10, so price isn't an issue. I'm also not sure what else to be concerned about when purchasing a domain name, such as domain registration, etc.

• I use 1and1 for my domains. Have been using them since 2005 without any issues. I have 10 domains with them now.

  Josh K : They are actually what I'm coming from (1&1 shared hosting). I'll look into them (again) for domains.
