Don’t Ruin your self your all the registry stuff just check you domain name availability in “www.domainsbot.com” and when it can be taken. Just visit any web that will gladly register your domain (any standard search option using yahoo or google can make it) or just visit

www.godaddy.com , www.afternic.com , www.dotpound.com.

Try to find the cheapest you can.

$1.99 for newby domain and around $7.99 for one year registry

Private advise: Godaddy cupon is here http://pacificcoasthellway.com/godaddy-coupon-codes/ and you can get $1.99 + 20 cents ICANN fee = $2.19 per domain for a year. The promo code is 199TEST. It works only for one new domain per account, remember for each account only.
