Is this any good? Makita with 18V, 3ah battery, and 101 odds & ends at Screwfix . I'm guessing bigger voltages and bigger batteries are better? Is there much more to considder? Spare batteries are hideously expensive, but I'm guessing a 3Ah battery should last a fair while as most others are under half the size?
Jobs that need doing in the short term:
Drilling pilot holes in carbon fibre and epoxy (I'm guessing my gran and a hand drill would be upto that though!)
Cutting a 108mm hole in some (not massively thick, <5mm) fiberglass (might be more of a challenge), then again I've no idea.
