Also I know this is in disagreement with some other people.
But your first airsoft gun doesn't have to be your last one. Pick up a good affordable cheap one, which sure it might not last 10 years but it will at least hold out for a season or 2. and once you get a feel of what you liked and disliked about it you can make a much more informed decision later and also pay the bigger bucks to get exactly what you want. And then buy a ultra/super/high quality made gun that will last 10 years that you can throw all your upgrades on.
Plus you never know you might spend 1k getting into the sport and go "it's not for me" and quit.
