Where to get a cleaner crew?

I'm looking for a cleaner crew for my new tank (I got it used, and there's a
lot of hair algae, some cyano, and a little green slime, but not TOO bad.)

I'm concerned about cost, reliability of delivery, and quality of the
merchandise. Any suggestions? Anecdotes? Experience?

I've been focussing on Garf, reeftopia, sal****erfish.com and marinedepot,
but I'm open to other suggestions.
