.ORG represnt you as a organization and that is good for company reputation. But with it I like to suggest purchase all major domain extension such as .com, .net, .info. So no one can divert your future traffic and it will increase one more star in your company reputation. That all extensions are redirecting to one common site.
For exmple
if you target on abc.org and abc.info,abc.com, abc.net all these redirect to your site.
