I've ran out of DVD-R discs and since I'm in the middle of a project, I need some new ones quick. It seems that CompUSA is having a sale on their 25 pack of -R media that averages it out to $1 a disc. I know there are currently three companies that make discs for CompUSA, PRINCO, LEAD DATA, and OPTODISK.

I was wondering if there are any particular methods of telling them apart. For example packaging, color, etc. I'm planning to get the 25 pack and really don't want PRINCO. I've had decent experiences with the other two so I really don't mind them. Thanks.
