css editor themes

Hi folks
I've been working on several Omega themes using a combination of Firebug, TextWrangler & Filezilla. My workflow is to tweak CSS with Firebug until it looks good, then open the CSS file in Filezilla (with TextWrangler) and save the edits back to server. No source control for this.

I'd be interested to hear what other peoples tools and workflows look like. I'm on a Mac (Leopard) and am looking around for a more functional Mac-based CSS editor if anyone has a favourite.
