I don't have a Knight, but my friend does. It has a laminated stock with the stainless steel metal. He's been pretty happy with it so far. However, he mentioned to me the other day that he's considering selling off one of his guns to get and Encore. Suffering from Encoritis apparently.
Shortly after joining this site I got hooked on the idea of the Encore Mulit-Gun. I originally bought the 209X50 for our muzzle loader season here in Arkansas. Now I've added a 24" .223 barrel and 15" .308 barrel. Seems to me like the Encore is a smart choice for those that don't want to drop about $500 each time they're looking for a new caliber rifle. Usually about $225 per barrel.
Your father may also want to look at the T/C Omega. It has smilar looks to a Knight (i.e. SS metal and laminated stock) but it's a falling breech type gun rather than a bolt. No manual safety on the Omega, just cock the hammer and you're ready. I think the Omega and Knight would be similar on price. The Encore can be had maybe a little cheaper depending on if it's blued or SS, wood or composite, etc.
