Domain or Blogger?

I like you wordpress, I really do.  BUT it is a complete pain to customize a layout and having to pay money!  I originally moved to wordpress, but now I feel like I should of either stayed with Blogger OR purchase a domain.  What do you guys think?

I already created a new blogger, but have yet to customize and might look into actually going back to Blogger and purchase a custom layout from someone.  We will see!
