For what they sell the maruzen P99 airsoft version for in Canada (if you can find it instock) you might as well get a full size AEG for a bit more or less.
eg $300 http://aasurplus.ca/airsoft/product_...roducts_id=184
got my JG36c for around that price, in fact cheaper.
If you still are dying for a p99 but are willing to SACRIFICE
not using it in games , you can get the CP99 pellet gun for around $190. Or even a CP sport for around $130. Can only use it for target practice but it is so much fun to shoot. eg mine is around 420FPS with 8.2grain pellets. But I have a 9" barrel hidden in a fake compensator. I love the damage it causes to targets.
