$13 Li-Ion drill driver.

[pictsidhe]

Lidl have 12v Li-Ion drill drivers on offer for $13 tomorrow. The chuck separates from the rest of it to make a really short driver. I'll likely grab one for awkward spaces. Could also be useful for cannibalising to motorise your flaps or something.
I've found Lidl stuff to be mid quality Chinese stuff. Not up to industrial use, but fine for occasional use. it's going to be hard to go very wrong with a $13 drill driver...
