I've had little success with Craiglist posts. One of the people who responded gave me the address to his trailer (yep, I said trailer, although to be fair it was a double-wide). He (the drummer) and the guitar player were much more interested in smoking weed than playing music, so the music fell apart pretty quickly.
The second guy who responded lived in an upscale neighborhood of Atlanta and had probably $40k-$60k of equipment (Marshall stack, Mesa stack, 5 guitars, full PA, mikes, keyboards, midis, and a set of pedals and toys very professionally mounted). His only problem was that he could not play. Unbelievable! Definitely a case of too much money combined with no talent.
The other people who have responded include people who can't wait to tell you how good they are, but they can't write a coherent message without lacing it with expletives. I have had a couple of pretty decent responses, but nothing developed beyond the initial contact.
