Where is the best place to find some good blogger templates? 

I use WordPress. They have a ton of templates and don’t be afraid to push the design as far as it will go. Tumblr is also good and well suited for mobile viewing, which is an important consideration now. You can see my site/blog at orionadvert.com.

Do you mean Blogger.com? They have some on their site, or you can Google them. If you’re just looking for good blogging templates, get WordPress.org (you need to host it on your own server), and then get something like Woo Themes, Elegant Themes, or Genesis. Those are all paid, but they are great themes.

@Jamericanspice, you can also put your own header in if you don’t like the ones that are pulling up from your profile.  They are easy to create in Photoshop or another imaging software of choice.  In case you need this info, the dimensions I used to change my header was 915w x 142h in pixels.  You may have to play with the dimensions a little depending on your image.  Hope this helps.
