When I was a teenager and early 20s I had a local gunsmith/dealer who made a great offer to me. He said that any gun I bought from him, he'd allow me what I paid for it in trade for anything else in the future, and if the trade-in was worth more than the next gun I got, I'd have the credit on my "account." What he was basically doing was giving me the opportunity to take one gun at a time of anything he took into his inventory, use it for as long as I wanted, keep it if I wanted, or swap it out for something else later. I got to try a LOT of different guns that way. My eventual keeper was a 1976 model SP-1 that is an excellent gun.
