Dang, and the logo is so pretty.
A nice logo shouldn't be the reason for any license.
And btw, there are several good reasons why NC is bad. One of the main-reasons against is, that (at least after german/european law) selling the products is completely forbidden, even if you cover only your own costs.
I know many good projects by local hacker/makerspaces you can buy there for something like their own costs for parts and pcb pluse a little additional fee, so that in fact the work of the members (creating the kits, picking all the parts, ordering pcbs etc) is paying some of the hackerspaces bills, supporting the community this way. Without these earnings, the hackerspace wouldn't be able to make soldering stations including reflow oven, measuring equipment and all the other expensive equipment to everyone interested.
But, in fact, if you calculate with normal wages and all other costs like a commercial company would do, these kits are still sold for less than the own costs.
And, on the other hand, contribution by others to your project get the same license. So, in fact, accepting contributions (imho one of the main reason and advantage of open source projects) will also stop you from being able to sell the project later without violating the contributors' copyright.
In my opinion, BY-SA is strong enough to enforce a 'good behaviour' of others using your project. They have to mention you as the original author everywhere and give back improvements. This way, they never can't publish your/the communities work as their own, and everybody else is able to use the work they put into it in further revisions. That's exactly what I want to do with my projects, give other people solutions for problems they can improve and use without any cost.
http://freedomdefined.org/Licenses/NC also summarizes some other points, but it's more about images and other "software".
I myself did use -NC quite extensively some years ago, but then decided to switch discard the -NC restriction for the reasons above.
