Ive got a couple regrets, and a few that did return

RBION, I sold it to a guy locally that plays it everyday and will never sell it back, havent found another (at a price i will pay)

Class of 1812, They just dont come around much, had 2 of them and was offered enough to sell thinking ill get another, that hasnt happened yet

Joust, head to head. Sold for big money at the time, which actually is still about what they are going for, just like the uniqueness of it.

But a good story of the one that got away. Sold my GnR that i bought for 500 about 12 years ago, sold it for 1500.00 Had to sell due to a divorce situation. About 5 years ago i was in the town of the person i sold it to, went and knocked on their door and asked if I could buy it back. 2100.00 later, it was in my suburban. Never plan on letting it go again
