I have actually had muhc success with the 3rd generation of G&G AEGS. I have the Scar-l myself, but my bro just picked up their GR16, which has been through a month's worth of games and has had no problems. Obviously this doesn't show ay long lasting quality, but I have had mine for about 8 months now and have now internal problems whatsoever. I wouldn't spend the extra money for the limited edition though, but that's just my opinion. Hope you find what you're looking for.
