Not sure of current offerings, but Kimber made their Super America with a quarter rib and an ebony forend tip - I would still like to get my hands on one of those!
As for classics, the Winchester 52 sporters get a lot of attention, but my favorite is my old Winchester model 69. The 69 had a Springfield type safety knob on the back of the bolt unlike the later 69A models.
This one my grandfather customised, and looking at the bore, there is no reason it should shoot as well as it does. This rifle has been the first shooting experience for just about everybody in my family and will be for many to come!
