Here's one that will do it all for just $29.99:

Or another option is get sectional rods and the needed brushes and pack them in a small tool or fishing tackle box
I prefer the tackle box due to the sections provided for small pieces and the lower area for larger items such as assorted screwdrivers
I wouldn't worry about a "shotgun rod" since shotgun barrels seldom need scrubbing like rifled barrels, and almost never need cleaning "in the field"
A light wiping will take care of the shotguns 99% of the time.
The best thing to use for that is a "Tico Tool"
They work great and will last a lifetime:
