"Go Airsoft Starter Package" Avengers BioHazard M4

So I saw this on Evike, and since I'm just getting into making purchases for the sport myself I was wondering if this was a good deal. They say it is fully upgradable metal V2 gearbox internals, and I was thinking I might get this to start now, and later on upgrade it how I want to have it for myself. I'm really thinking of getting the Umbrella Version 2 Full Metal Receiver by Madbull, for the design logos and such and just kind of build off of that. I know that just getting an Umbrella gun itself is expensive, but I'd like to see about having that kind of branding on my own gun that I built. Does this seem like a good way to start, since I would at least have a gun to start with, and can just build around it as I continue to play, or should I just look into getting something better, and not worry about teching like this. I know I like the sport, and I know how to solder if need be, and feel like it would be a good long term project, while still being able to use it to play.
