I've been thinking about this for a while but a recent death of a beloved cordless drill has moved this into the forefront a bit 
So I'm now looking to get a cordless drill and I'll probably at the same time an impact wrench to go with it.
For my uses honestly I could probably get away with any old cheap chinese stuff but the thing that I'd like some advice on is the 'ranges' essentially, so looking at things like the Milwaukee M18 stuff which includes the basics like drills and impact wrenches but also has angle grinders and torches and air compressors and sanders and polishers and etc etc etc, but what manufacturer has the 'best' range and I guess what manufacturer is most likely/proven to add to/expand that range over time?
I'm posting here because although the drill is more used for DIY than motors the majority of the tools I'd probably end up buying are for car maintenence/repair etc so more focussed on that side of things than say a more DIY focussed range...
Any thoughts?
