I spent a day at the Huaqiangbei market and honestly there's very little like it in the world. I didn't go in looking for anything in particular, but left with all sorts of tools and parts that I didn't even know I needed. A full USB power debugger with colour screen ($8), various LED module samples, a few Android tablets with a 9" screen, dual SIM and microSD ($30): my friend had his iPhone upgraded from 16GB to 128GB storage (a student literally desoldered the flash with a hot air gun, transferred it over in a BGA reader and soldered a new chip on, in under an hour)... as well as a whole number of little parts and cabling and components I didn't even know existed. Others have written more about it (https://shift.newco.co/2016/10/13/what-50-buys-you-at-huaqia... is the classic article) but if you're even faintly interested in electronics I'd wholeheartedly recommend it.
