I Need A Banner

I thought i didn't need a banner until my small (but growing) website gained some reputation and i decided to exchange traffic with a few fellow sites,it was by then that i realized i needed a banner (reasonable size,about 33x80 or bigger),but it was by then i also realized that i really aucked at flash banners (well one has many gifts right?).
Sop that's why i ask if any of u know anything that would make me crate a good banner (a program,a tutorial,whatever)

thx
