Looking on Ebay the going price for a used SE vs Series 5 is almost identical at ~230$ US (yes I realize that these watches come in all sorts of conditions). Taking this into account I'm wondering if there is any better bang for the buck than a used 5. I purchased my first, a 3, used, and the one scratch it came with only removed any hint of worry about that second scratch. It continued running fine until the end but I got tired of wiping it to clear storage for every OS update.
