not sure why so many people pimp 99designs. It's on the author's "priceless" list, but it's the only tip he spends 6 bullet points instructing how to overcome 99design crap. I tried them once, spent a lot of time collaborating with designers and was not impressed with any of the results. I had to file a chargeback with my credit card company because 99designs refused to refund my money outside their 60 day policy (I was unaware I had 60 days, you have to hover over their money back guarantee to find that out). I could be spoiled, as I've worked with a good designer in the past (http://rohdesign.com/) -- the benefit being more focused attention to your project, albeit for a few more $$, but not really when you factor in the value of your time.
