As a newer airsofter, in my limited experience there are 2 things you do not want to cheap out on - eye protection, and your gun.
Nothing kills the fun faster than your gun not working. If it's all you got and it goes down your day is over. Even higher priced guns will have hiccups that need to be worked out. You're AV'd, there are lots of options in the classified section for quality guns at very good prices. Don't go cheap - you can have lots of fun with a working gun, 1 high cap magazine, and solid eyepro. You can't have any fun with no gun, unless you're lucky and someone has a loaner.
It hasn't taken long for me to learn that buying cheap usually means buying twice.
