Have a look and see what else is available in the range for different makes, you might want to add a jig saw or impact driver a later date for example and save money by using the same batteries.
I have a load of old Makita 12v stuff, combi drill, sds drill, torch, 1/2" impact, planner and radio (though this will run on different batteries)
I like Makita as they have a local stockist, when i had Dewalt stuff i ended up doing around 160 miles taking something back under warranty so local is also something to consider.
