$9 gets you a domain name. So just do it!
I've been using GoDaddy to register domains for myself and for my clients, and I'm really impressed with their service AND with their prices. I keep seeing submissions from bands with domain names that look like myband.blahblah.someothersite.net -- stop the madness! Drop NINE DOLLARS to get your own domain name. It's something you will HAVE to do if you want to get to the next level. No question.
