I have a Mossberg 500a that has a 5+1 capacity and was wondering how or if I could increase it somehow without getting a new barrel and magazine tube?

Knoxx makes a ten round drum adapter but it is high ($200)

Unlike the Winchesters and Remingtons, the Mossberg 500 cannot have its magazine extended. Getting another shotgun would be cheaper than the Knoxx conversion.
