Hey acejack, I'm not a fan of those kinds of those pre designed logos since thousands of people may have the same logo as you, though I was checking this logo-corner and it seems you own the right as soon as you pay the logo, which I find really interesting plus the logos are cool. Thanks for sharing the page.
Yes, that is great! That was what I liked the most. So as you noticed, to get a pre designed logo is not so bad. In fact, it would be even better.
Are you wanting a funny logo or a logo that represents your product/service. off the shelf logos are usually dull and do not offer longevity. Think of alogo that stand out to you and I guess that was not off the shelf. Do it right from the beginning and as your brand grows your image will not need to change.
