If it's a kamikaze thing.. The alternative is a world of e.g. dogfighting drones with a small weapon mounted on the hunter. Think of it as a lightweight airborne AA gun. There you might justify a higher price with e.g. the hunter having a >80% likelihood of surviving an encounter.

Maybe no need for a gun even: dangle a detachable rope or web underneath your drone, now you just need to be fast & maneuverable enough to catch the other drone, and tangle the rope into its propellers.
