I have two sets of pipes. The ABW Kintails I carry in a "conventional" pipe case, bought from a Highland outfitter about 10 years ago for $60. My poly Dunbars travel in a tool box I bought from Home Depot for less than $20 about 2 years ago. Sturdier than most pipe cases I've seen, plenty of room and the top tray lets me keep the smaller goodies, hemp, reeds, tape, etc close at hand. Right after the holidays, I bought a set of "Parlor Sticks" from Pipeline to use with the Dunbars. They're a set of smallpipe drones and chanter that plug into the stocks on your GHB, gives a bit more versatility. There's even room in the tool box to carry them along.
Might be worth looking at a less expensive (and less conventional) option.
