Thanks for the info! I bought my domains last night. I am hosted by Blogger and am going to continue with Blogger for right now. I need to switch things to the new name but am SOOO nervous to screw it up!!!
I'm with blogger and I my domain name is registered through Go Daddy. It's $10 a year. I switched during a time when the only people reading my blog were my sister and MIL so I didn't lose anyone in the redirection. I think Google/Blogger was partnered up with Go Daddy and they kind of chose them for me, which was fine because I knew nothing about domains (still don't!).
I bought my domain through GoDaddy a few weeks ago and it was insanely simple to set up. My blog is hosted on Blogger and it redirects right to my URL www.pinkvanillacupcakes.com. :) For $10, it's so worth it.
