I got a G&G GR16 as my first AEG for $308 + shipping from buyairsoft.ca and I recommend you do the same for your first AEG as well. I have had it for a couple of months now and I play airsoft a couple of times a week and it still shoots hard with no problems at all, but that could also be because I haven't owned the gun for a long enough time to tell. I still am a noob and wouldn't really know exactly what a good quality gun is, but it's lived up to my standards.

Also I got a sniper from the same site called the TSD Type 96 (The site calls it the "Ultimate- Bolt Action Sniper Rifle, and the Warrior L96). I like the sniper, but I can't compare it to other snipers since I am still fairly new to airsoft. I would say save up, get a high quality AEG, and if your still interested in getting a sniper, invest in a high quality sniper. The sniper shoots hard, and prices at $320 + shipping.

If your age verified, look around on this site. Do lots of research and maybe take a look in the gun review section.
