I have registered the domain technologytales.com for this blog yesterday and have since got the DNS configuration completed. I used Easily.co.uk for the registration; they also host my other domain name and have done so since I first registered it. Easily allowed me to transfer to the WordPress.com namespace servers and $10 secured the rest of the setting up and $10 every year at renewal time with keep things in place. There is more about doing all of this on the WordPress FAQ.
