Honestly, all my Centrotec stuff was bought piecemeal over time from both Festool and third parties. If you think that the assortment will meet your needs, then the kit is a nice setup, including with the Systainer. At the time I was assembling things, Festool wasn't supporting square drive, either, which is my primary screw type and has been for two decades. So I had to go third party there (Snappy), for example.
