In all serious though, I was sort of the same to start with, but once you handle some of the full metal AEG's especially the mid-high end ones I was easily turned.
I will get a Gbbr eventually but not until I am more experienced in maintaining cleaning etc. If you got the budget get a mid-high end aeg to start then add to your armoury by going Gbbr once you have some game time under your belt.
