I bought 3 H&R/NEF single shots, in various conditions, for around 150-170 total.
Barrels were cut down to a handy but legal length, the front sight was reinstalled and a HiViz fiber optic sleeve was slipped over the barrel. A set of sling swivel studs and a slip on neoprene shell holder later and bang, a perfect camp gun that doesn't get screwed up if the gun goes over when your canoe tips (having a line attached through the rear sling swivel stud keeps it from being lost in one of the famous internet "boating accidents").
ETA- I gifted the guns to my brothers and a good friend. I have yet to make one of my own.
