I don't want to shill for any one brand/maker, but Walsh shuttle pipes are also something to consider. They use plastic reeds and come in two or three drone configurations. (The 'drones' are all in one stock - the shuttle - not separate pieces). I have a two-drone set and they play very nicely.

There are also a couple of other options - I've heard tell of practice pipes and Fairylore (may be a brand name) or parlor pipes.
