In many ways, I consider my Star sets to be my personal customs. I was unwilling to sell anything to fund them (in case they never arrived), so I borrowed the money. I've sold off several sets since (to pay off the loan), but not until long after the Star chips had arrived, and I could effectively over time rank all of the sets in order of long-term preference.
Do I regret the sets I've since sold? Yeah, a few -- several sets sold were essentially irreplaceable. But in my collection, they were redundant from a play-perspective, they all went to good homes, and I'm happy with what remains. I'm still in the process of thinning the herd.
