GoDaddy Domains is the clear winner when it comes to domain registration.  They include a whole list of extras at no additional charge including:

• FREE InstantPage website builder
• FREE personalized email
• FREE "Parked" page if you aren't ready to go live yet
• FREE domain forwarding and masking
• FREE email forwarding
• FREE photo album (with or without password protection)

The features at GoDaddy Domains are exceptional:

• Getting Started Guide
• Total DNS control
• Domain locking
• Auto-Renew protection
• 24/7 Technical Support, Sales & Billing
• Status alerts on changes to your account

Auto-renew is a critical feature if your website has brand-recognition.  When a domain expires, it is available to anyone who reserved it or anyone attempts to register it.  If someone gets to it before you renew, you could spend a tidy sum of cash to "get it back" in your hands.

GoDaddy Domains phone support is timely with most calls being answered within 10 minutes.  Their staff is knowledgable and courteous and they will find your answer no matter how long it takes.
