Are you looking for Remington brand choke tubes only? Carlsons and Hastings make high quality choke tubes for Remington shotguns.
If you are not in a hurry check ebay. There are regular sellers on there that if you wait until you get them for the opening price you can get a heck of a deal. Otherwise this is as good as any. http://www.ableammo.com/catalog/default.php I wouldn't go out and buy high dollar aftermarket chokes until you are dang sure you need one. RemChokes are probably the best patterning factory chokes out there.
