I plan to buy a second hand Switch. Stores here let you check out 2nd hand stock and basically test in the store, just to make sure it's good. All I gotta do is ask to see it, check the firmware, and if it's not a vulnerable one, ask to see another. Thankfully, the store I'm currently work in has a whole bunch people traded in at launch. They bought them, and immedietely traded them in for cash, making about 100 euro's. More expensive, but with my 15% discount, It's only about 10-15 euro's more for a second hand one than to get a Brand new one. Plus having 3 year's guarantee, I'm safe if something goes wrong.
