Bosch set is on amazon for usd99, free shipping to HK. It's ultra compact and great for adhoc whatever since easy storage. Too bad i got a cheaper china set already but don't want them in landfill yet.
Corded/less 12v/18v impact/hammer/x drill/driver combos are all great but very different things.. good to start with 2nd hand to see what's really needed. Note that no brand tools battery generally die in a year or two.
