My 1200 was about $150 from my local gun store years ago. The LGS acquired a crate of unused 1200s from a western state police armory when a change was made to a different shotgun. The 1200 had a small, engraved, numbered metal tag on the stock indicating it belonged to the state police. It also had cosmoline on the innards that I had cleaned off by a gunsmith.
I consider my 1200 to be one of the best values I've found, and I don't see the need to change anything from original equipment. My only regret is that I didn't but two when I had the opportunity. I even like the state police tag.
