I've had an 1100 for 15 years or so--killed lots of birds and such. Walnut stocked models in great condition may bring $400, but not much more. If the extra barrel is a cylinder bore slug job, it doesn't really attract much more. It's also a 2 and 3/4" chamber. That doesn't hinder you if you have screw in chokes and are willing to buy a premium tube to improve your chances. Most will outshoot 3" loads in standard tubes. That being said, I've always been a pump man at heart, and the Nova will always be more versatile and reliable. Your choice on two great guns.
