Used is Ok. Buy used from a reputable place like Reliable. They will stand behind used stuff. If it is junk to begin with they won't sell it. I enjoy used stuff, sure I got ripped before but overall it has been good. If you are into old levers you don't have much of a choice but to peruse the used market anyway. As for calibers I would recommend the 30-30, 303 brit or 6.5X 55. Stay away from Magnums as afirst shooter. Work on shot placement/ accuracy. Know your gun and what it can do at different ranges. When it becomes the 5th limb you are good to go!
