Regretted selling my Tomcat. At the time I had spent so much time fixing it up, I just couldn't stand it anymore. Sold it and then couldn't stop regretting it. But ended up getting a fully restored and cleared one to replace it. On the other hand, sold my LOTR. Felt some regret after a few months. It was just so pretty. But found one on location. All it took was hearing, "the path of the dead!" to remind me why I sold it. After two very long games, I walked away leaving credits on the machine. I was at peace. I just played that game way too much when I owned it. I just don't need to play it again. So, seller's remorse cuts both ways.
