I get the desire to have some funky European tools. I have some including sockets, but I can't recommend them. You just can't beat Craftsman. Especially if you are working on bikes. You may end up grinding sockets for special purposes.
And if you honestly break an unmodified socket on a Sunday afternoon, you can go to Sears, and they will GIVE YOU a new one, and you get back to work. In 20 years as a shade tree German car mechanic, this has only happened twice. But in both instances, Sears was a life saver. And they are probably near by and open at night. I have a massive collection of Craftsman. I have used other brands (snap-on and Euro models etc) and I like Craftsman just as much. And you can't beat the price.
As for sloppy fits on the drive side, a common complaint, I've never broken a socket there. Most sockets will break on the socket side. In my opinion, a little looseness on the drive side serves as a slight wobble, making the tool easier to use. That's my opinion.
