I've got all kinds of them. Marlins (1895 and 1985 Cowboy), Sharps, Rolling Blocks, Ruger #1's, you name it.
I like them all, shoot, you can even get a TC Pro-Hunter in 45-70. There are MANY choices out there and it will all depend on your buget. If your not picky, you can find a Marlin's for $500, Handi Rifles for WAY less than that. Rugers are $800+, Sharps (Shiloh) are $2000 or so. So it just depends on what your wallet can stand.
I purchased a 1978 Marlin 1895 45-70 (Highly Desireable, no hammer Block Safety) last Friday for $550 in the local Classifieds. If you do get a Marlin, Make sure it says (JM) on the left side of the barrel right in front of the receiver. That lets you know it's an ORIGINAL Marlin.
