Where to buy cheap devices to practice disassembly and assembly skills

@iam51515 this will very much depend on where you are located. In my area, I get devices from local recyclers as well as places like Goodwill for relative cheap prices. I also frequent local pawnshops that often run specials on broken items as well as items that they can't sell. Yard sales and flea markets are another good source. Dumpster diving is always a fun thing to do as well :-) Just remember, do not be picky and do not be to selective in what you are looking for. If you are only looking for one type of device i.e. cell phones etc. then you just limit yourself. Keep and open mind and always keep your eyes open. There are lots of good deals out there and lots of opportunities to learn
