Some brands, Teng for example, are in my opinion expensive and if you know where to look you can get Gedore or Hazet (German made) for similar money and there is no comparison whatsoever.
Carolus and Vigor are Gedore and Hazet's cheaper lines (Taiwan made like Teng) but still good stuff for the home mechanic.
You'll be hard pressed to get all the sizes for the TC in 3/8 drive alone.
