I have one of the early SBL's, a JM-marked one, and it is one of my favourites. When they first came out, I took one look at them and scoffed. Who in his right mind would defile a levergun by making it out of stainless, let alone adding a rail and a laminated stock? Then a low-mileage, like-new specimen showed up at the local shop, and I looked it over. The price was right, I took it home planning to hate it and sell it off quickly...and I fell in love. Mine is set up with a couple of scout scopes and a conventional scope, all in QD rings and instantly interchangeable. I will never sell this gun, while a bunch of other more traditional levers have gone down the road.
Sure, get a Winchester 1894 in .30-30...it'll make you that much more appreciative when you get the real deal: a Marlin in .45-70!
