Is airsoft megastore a good airsoft website? Is this a good gun to get?

If you want this, I would not say no. This is a great gun for annihlating the competition. A little high on fps, but that is because it is a support gun, which is meant to be longer range. But if you are really new to this and aren't in a group that does this at high FPS you may not want to get this as it is on par with most snipers for power.
