Get nicked with this Nicker Claymore mine available at Tiger111HK and it just costs US$59.00, shipping not included of course. It is activated by a wireless remote control (with no indication of radio range) and operated by a 2 x 9V battery. It can fire up to 200 BBs, and we suggest that either you reuse some BBs (not barrel to jam), or those cheap`o .12g BBs, or still just use some talcum powder just like the other airsoft Claymore mines in the market.
