Have had a Remington Nylon 66, Apache Black and chrome, since about 1974 or so. Paid 69.00 dollars. I know they have appreciated well, but I have heard many different opinions on them. Have thought about selling it. Some say it will develop problems and to ditch it. Others tell me it is the greatest thing since sliced bread, and I'd be a fool to part with it. Why such wide ranging opinions? Your input greatly appreciated.
