but you're really not gonna get any better than textmate or sublime text 2

Text wrangler is particularly nice.

Another vote for Text Wrangler. I use Sublime 2 and Texmate a lot but if someone wants a free solution and not interested in Vim or Emacs then I always recommend Text Wrangler. It's from the same people that make BBedit.
