Don't buy Milwaukee!! I've known four guys who've bought them and each has had to send them back within three months. Their service is awful, the tools aren't 'tough' enough and the batteries don't last a full day. Makita dtw285 seems to be the boy! I've got one and it hasn't put a foot wrong this far. Useful in the wet, 5.0ah battery has tons of life and the power of the machine is far better than the equivalent hilti, Milwaukee and Bosch offerings.
Most of all, great value for money too.
