After my 3/8'' Drive set, I'm working on the 1/4'' Drive 12 Points Metric Set. Already have the shallow, semi deep and deep 6 points Metric 1/4'' Drive. After that, it's onto the 1/2'' Drive in 6 Point and 12 Point Metric!
There's no putting down Craftsman, they make great stuff as well. I've used them before and have passed them onto friends and family. It's more like, whatever you want, just buy it. I may get bash for purchasing 6 Point and 12 Point in 1/4'' Drive, 3/8'' Drive and 1/2'' Drive from Snap On, but oh well. At the end of the day, it's you and your tools. You gotta start somewhere, and end up somewhere.
