Thought about buying used? Both of my guns have been used and I've not had a problem (Granted my 2nd gun I completely changed the gearbox). Most internal parts on an aeg are relatively cheap to change if theres a problem. You could save yourself a bit of cash buying used and getting your gear separate rather than a package and it would probably be a better spec.
I find with most hobbies there are always "starter packages" availble but what they put in the package you will end up replacing after a couple of uses as you find the quality isn't very good.
