Can't say I regret selling/trading any, as by the time I make the decision for one to vacate I've had my fun with it.

I do regret not buying a closeout Steyr Professional NIB for $500 when the SBS launched. I also regret not buying a used Merkel 47 20ga for ~$1,500 circa 2002.

I can walk on water.......................but I do stagger a bit on alcohol.
