the domain itself doesn;t really get traffic. its the marketing and promotion that gets you the traffic. but i try to use my main keyword in the domain, that was it give me a little advantage when it comes to SEO
I know you said you know about GoDaddy but I say that normaly you get what you pay for. GoDaddy has worked well for me but sometimes getting domain names from your host can be cheapest, however some of these realy cheap domain name services have odd terms of service in which you can't transfer or they can jack your price up quite a bit the next year without you being able to move it. Whatever you do chose, the cheaper the service, the more important to *read the terms of service*
