Personally, I am quite on the fence regarding the use of a crowdsourcing site for a logo design. It is still a touchy issue for most designers who said that crowdsourcing is a no-no for obtaining a logo design. I have tried crowdsourcing before and I know the risks involved but it comes within the territory. But there are other no-frills logo design websites online such as http://www.logobee.com, http://www.logodesignstation.com, logoyes.com, etc. which are actually great in getting a professional logo design at a fraction of the price and minus the risks of crowdsourcing (plagiarism is one of them). Seeing that there are no consultation services, the price is significantly lower than that of conventional design firms. For instance, I have tried http://www.logodesignstation.com and the experience was indeed a positive one. I managed to get my business logo design at an affordable price and the turnaround time was great as well. Highly recommended. Although crowdsourcing for logo designs could be a bane for some, many find it to be a viable alternative to get a fast logo on the cheap. It all depends on the individual actually.
