I've thought about registering a domain name for a future website for my company. I may not do it for a while (if ever) but it sounds like it is not a huge expense to claim a name.

I don't have a clue how to go about this. A google search turns up anything from $10 to $100 a year but I'm not sure what is legit and how one compares with the other. Anybody ever start a website? How did you do it?
