I just got an Arduino Mega beginner plus 37 sensor kit for xmas. I'm really excited to try out some of these different tiny SoC gadgets, especially looking at trying to build a basic hand-held tricorder since that has been an obsession of mine for a while. I also want to try out the mesh networking with either the ESP8266 or ESP32.

All my gifts were bought from Amazon, mostly for the speed of shipping and arrival. But I may just look closer at aliexpress or banggood to see what they have.

Thank you for sharing the link!
