You can create an account on Amazon.co.jp and buy direct from Japan. Buying more things at once lessens the shipping cost pain but still cheaper than US Amazon or DRPD. I just received 2 Nepros ratchets and they are nice!
I would consider adding a 3 pc set of the Knipex Cobra pliers and a Gerber multi tool for needle nose capability and knife. I have a go-bag just for the jobs you mentioned and almost always need the cobra pliers for something. The twin grip ones are also quite handy for buggered-up screws
This is the best one I've found. I like the solder feed wheel. Great for under dash work in tight spaces.
