For a couple months during the last year I had a phase where I really wanted a Marlin SBL. .45-70 seems like a really fun caliber for the handloader, and its conducive to bullet casting, which I wanted to try.
Anyways, I looked at ~10 of them over the course of those months, probably 5-6/10 were at large sporting goods stores, and the other 4-5 at local gun stores. I was prepared to pay $750 for one w/ tax....
...And I wouldn't consider spending anywhere near that on any one of the rifles I looked at. Every one had very poor craftsmanship... The actions almost always felt rough and sandy (which could be fixed with polishing and lubrication I'm sure), the rail was sometimes visibly torqued (2/10 rifles), the edges on the lever loop were sharp enough to remove skin if I were to attempt to chamber rounds repeatedly without wearing gloves, and the edges around the ejection and loading ports [if that's what you call them] felt like the edge of a rough serrated steak knife. I don't want to bash Marlin just to bash them- I'm just presenting my experience. With exception of the twisted rail, the rest could be fixed fairly easily, but if those cosmetic flaws are indicative of the overall quality of the rifle, I wouldn't want anything to do with it. I'm sure there are a million FANTASTIC new production Marlins out there... but in my search I certainly didn't encounter one, and I certainly wouldn't advise anyone to spend money on one if they haven't handled it in person.
To satisfy my desire for a large-caliber stainless/laminate gun, I special ordered a Ruger super blackhawk bisley hunter instead, and I couldn't be happier with that decision.
