What purchase or purchases do you most regret? For me, it is my game used base from the last regular season game in the Astrodome. I paid $750 for this third base from this historic game. It might seem a good price for a base until you realize they changed out bases every half inning. That means there are 28 bases out there, 36 if they changed out home plate every half inning as well. Mine is 3rd base from the bottom of the 7th. Right now I don't even have it on display. I have no place to display it right now so it is stuck in my closet. I know I could not get $750 on Ebay right now if I tried to sell it. Hopefully one day I can find a place to display it.
