I got my 3DS XL as a refurbished product from Tesco Outlet, for £119. I was skeptical of its state for such a low price, but I received it yesterday and for the life of me I can't find a single scratch (though the screen is definitely covered with my fingerprints now!
Only thing I found baffling is that I updated my software, and patched my Pokémon Omega Ruby game, only to find the entire console would freeze, and I'd have to force it to turn off. At first it was 20 minutes into playing, but gradually as my patience was worn down, the time between each freeze got less and less.
I really didn't want to send it back to Tesco, so I tried doing other things instead. I discovered it only froze when I played Pokemon, so I put a different memory card in, and this time didn't patch the Pokemon game. Problem solved.
Other than that scare, brilliant product, great size, I look forward to expanding my game collection, 4*
