I've just bought one of these:

I realise that this is not for professionals, however for the DIYer it is perfect. I love the way that the chuck pulls off to reveal an integrated screw bit carrier. You could have a drill bit in the chuck then quickly remove the chuck with bit still in it, then snap a screwdriver bit in. So much quicker that moving between a drill bit and screw bit in a conventional chuck. It also has a two speed gearbox, so high torque for big screws. Three year guarantee and the quality seems far better that the usual budget stuff.
