Where I am in Canada, for whatever reason Whistlers were very seldom found and nearly all blasters that used Whistlers came packaged with Sonics instead. I only own three Whistlers, which came from a Switchshot from EB Games.

You couldn't even really find them in ammo packs, only just before discontinuation did they start to pop up.
