One showed up in a LGS today, has the button safety, unfortunately, but does have Ballard rifling rather than Micro Groove which is a plus. They are asking $499.99, which seems like a good deal. It had scope bases and wasn't mint, but was very good.
Is this a good asking price? One of the Marin levers in .45-70 has been on my "someday I will have" list a long time and I have gotten the itch to do more with the .45-70 lately.
