Used Thinkpads are a great purchase option, enterprise quality Thinkpads are often purchased in bulk by corporations, barely used, and sold for cheap. The only think you need to be careful of are stolen Thinkpads since they might get remotely locked.
Condolences for your daughter and wife. I know the feeling of loosing them as I already lost 4 smartphones, 2 laptop, 1 PC, with important files and memories within them.
Damn bro, although mine wasnt as bad as yours I also had some bad luck so I can sympatize a little bit. My wife(PC) also died last week and I had to replace the main drive with a new SSD. My phone also slipped from my hand and almost broke completely... I'm also a fellow Indonesian so that's another trait we share. WKWKWKWK.
Hope both our lifes get way better from here on out! Cheers and thanks for the translation!
