I don't know if they (NEF) will still do it, but they used to credit you the $30 the extended choke tube cost's, if you don't want it. That would bring the barrel cost down to $58 (Incl. fitting & shipping back to you), plus the cost of shipping to them. I doubt that you can get a barrel cut and threaded for tubes for less than $75. You would still have the standard barrel to sell, or whatever, and you may be able to recoup another $35 - $40 or so on it by selling it in the classifieds.
Might even get them to do a trigger job on it while they have it? You will first need to determine if the gun is new enough for them to fit barrels to it, must be newer than a 1987 and have a serial # that starts with a N or H, IIRC.
