Hoy Airgunneros (Tagalog)...chronograph ?

Guys I'm probably sponsoring an AG comp. in the PI this year and am looking for the cheapest chrono I can take over there from stateside here. Any ideas? Probably something they can also use for 22 LR as well--salamat (thanks!)
Are you looking for a chrony to get "official" readings for all competitors -- like for verifying their rifle is under a certain level of muzzle energy? OR are you just wanting to have cheap chronographs available for club members / competitors to buy or borrow? I'm trying to get a full understanding before recommending anything.
