Professional Logo for Software Company (Guaranteed Winner)

Need a professional web 2.0 logo that can be used in the banner on a company web site and on business cards.

Cogent Software

Cogent Software, LLC, provides software consulting services to architect and develop custom enterprise software applications.  We need a professional, web 2.0 logo that can be used in the banner on our web site and on our business cards.  It should look good scaled down on business cards or if printed in black & white.

Cogent means:

   1. Reasonable and convincing; based on evidence.
   2. Appealing to the intellect or powers of reasoning.
   3. Forcefully persuasive.

Just something to keep in mind when designing, but we don't expect incorporation of the meaning into the logo.

Here are some sites whose logos we like:
