I've owned 2 Winchester. Both functioned flawlessly, one was accurate, one was not.
Moving over to Marlin I wouldn't hesitate to buy an older one but in recent research for a friend who is looking to by a new .30-30 it seems that the new Marlins have fallen on hard times and the Mossberg 464 is now preferred for reliability, accuracy and function. Kinda strange cause when the new Mossy's came out they were kinda dumped on. They've gotten better, Marlins gotten worse, pick your poison. Personally, I look hard at the used market.
