Ever sell something and then wish you hadn't?

As I was packaging up my leader prime, I started really thinking damn, I'm gonna miss this guy. I loved the way I had him looking. I'm just hoping I can make myself another and be as happy with it. The money is nice, but he's got sentimental value now.
Anyone else ever sell one and get remorse before he's even out the door?
