Two drones. You get the essential harmony of drones which is half the point of bagpipes.
Be easier to sell on, too, I would think. Well set up pipes should not use much air.
Dry reeds (bellows) last much longer than wet blown (mouth) ones. Less replacement costs. Bellows can be transferred to another type if you decided to take up other pipes - and if you get hooked, you will!

Older pipers tend to run out of blow eventually - bellows are easier to manage in this situation. Might be an issue, but that's for you to say.
