Sometimes it is easier for a manufacturer to go with an existing tool storage brand and just rebrand than build their own. This seems pretty clear when you see all the different variations of the Systainer. Personally I think Systainers are great for organization but are a bit weak for the job site environment. I have a Mirka sander that came in a Systainer and the case was cracked just from shipping. Check out Systainers over at Amazon.
