I had a hard time finding some at a decent price. Through my searches and review reading I ended up ordering one from 'keep shooting'. They are located in the US though. It was over a year ago and I would not hesitate to order again or order more if I felt I needed more than 2 mags for my mosquito. It has been flawless and is almost identical to the factory one. If memory serves me correctly I think their shipping was a bit high at the time, I ended up having someone re-ship me the mag who lives down there and was still cheaper than having it shipped directly. Not sure about current costs and such. Just wanted to share my experience. Hope that helps and good luck. Despite the negativity people have towards the Mosquito I really enjoy mine and don't regret the purchase at all. I recently did a trigger job on mine as it was acting up a bit but enjoyed the process. A few more mods planned as well.
