The rifle in my avitar pic is a Marlin 336 A. It was bought a year ago, new, for $425 at a Big 5 sporting goods store. It is an amazing gun.
It is not legal for any CAS events so far as I know, but it's a keeper. Long range accuracy is impecable as is close and it's solid as a rock. The 336 can also be had in a "C" model, which is a little more expensive, but supposedly more period correct in the small details. My rifle provides the best open site shooting I've ever gotten out of a 30/30, it's definately one to bring into the family and treasure.
I'm sure Henry enthusiasts will scoff, but that's my 2 cents worth.
