Do it, once you go GBBR AEGs are never the same. I run my GHK AKM and my MWS almost exclusively now. I haven't used an AEG in over a year and don't even consider buying a new gun unless its a GBBR. Limits your options and therefore spending quite nicely, though I am soooo tempted by an MP9, GHK 553 or VFC G3.
