Where to find a 3.5" 870 express 26" barrel?

[duck slayer'er]

Does anyone know where I may be able to find a good used or aftermarket 26" 3.5" rem 870 barrel? My gun came with a 30" which is great for geese but I want a smaller barrel for turkey hunting. My local gun store can get me a new remington barrel but it will cost me the same amount as the whole gun cost me...
