Well, there's ISBoxer ($10 for 90 days, or $36 for a year). It was a little bit tricky for me to set up, and I consider myself relatively smart on computers. Could have been the beer. Once it 'clicked', though, it was mere minutes to set up my other teams.

There's KeyClone, which I've used about 3 years. It takes minutes to set up, and is still a very nice software. It's $20 for lifetime.

There's several free ones, but I believe they all require scripts, but premade ones are usually found pretty easily.

Then you have the single must have: Jamba. It's a WoW addon that automates a lot of tasks inside WoW, such as your slaves doing the same thing when talking to quest givers, selling greys, etc, etc. It's free, of course.
