I have had a set of these for years and use them a fair bit
All of the drills and driver bits have been replaced many time but the main components have held up well,
Trend and Makita do them. The Makita one used to be the best as it is smaller in diameter than the Dewalt and had nicer countersinks. However, they seem to have changed the design, used to be a nice brass collar and would last well. The one I got last time had an aluminium collar and horrible quality control, I sent it back and have the Dewalt at the moment, it's fine but is too thick sometimes. Trend have quality issues as well.
