Like a lot of people, I got a Raven .35 for $50.00. From my brother, who inherited it when dad died and didn't want it any longer. Good little shooter, lives in my medicine cabinet.
Otherwise, a Ruger MkII Target for $125.00. My first gun. I still have it, twenty odd years later.
There's also the Marlin Papoose I bought for $80.00. I got it after I watched the gun store owner pay a guy $40.00 for it. I waited until he left the store, then asked if the gun store owner if he'd like to double his money. He said yes, and he appreciated how I'd done so, not overbidding him in his own store. Good manners sometimes have their reward.
