I used 99designs for the logo of my latest project and I'm very happy with it. I put up a content and set the prize to $150 (+$39 that 99designs charges) and I started getting logo submissions within hours. By the end of the 7 day contest period I had received 30 submissions from which several were really nice. I highly recommend it for logo designs. I chose to put the contest for the logo, and then work off-line with the winner to do the rest of the design work.
