I would like to interject into the fray and recommend a different course of action all around. My first AEG rifle was an Echo-1 G36c and it has served me well. It is a little more than four years old and it is in the exact same condition today as it was when I bought it. I have had to do nothing more than general upkeep. I have not replaced or upgraded a single piece on it since the day I purchased it. In other words, it is has been an excellent gun and I would highly recommend an Echo-1 any day of the week. I paid $169 for mine and it has been the best investment for the money.
Compare this to my second gun, I paid $199 for a SIG 550 it's technically a Cybergun, but it is actually a JG rebrand. It has been nothing but trouble. It has broken several times because the externals are cheap plastic, the internals are good, but the body has broken twice and the stock as well. I replaced the entire gun once and now both guns set broken and inoperable. One is completely parts and the other has no stock again.
On the other hand, I own two ICS SIGs a 551 and 552 and these have been as reliable as the Echo-1, but these were over $200 each. The only issue I have had with the 551 is one of my friends broke the flashhider off it, but that was an easy fix, I just removed the broken one and replaced it with a spare M-4 style I had sitting around in my spare parts.
I also own an ICS GSG-522, which is basically a better built MP5, and I have to say I am in love with this gun as well. I paid $169 for it and cannot complain, it is a well built gun and will last quite a while.
Compare these to the two A&Ks I own, an M60 and an M249 and these two guns have been a pain in my side for quite sometime, but there is more to this than just basic quality and workmanship; in other words, their issues are a long story.
What I'm trying to say is, there are plenty of options out there, do some research, talk to people, but don't get caught up in the hype of the name and the fanboy mentality. Just because its popular doesn't mean its worth it. Many of the guns I mentioned are great starter guns, they will last if they are taken care of, but not even a Tokyo Marui will hold its own if it is abused and neglected.
