Well from your other two posts inquiring about an M4 and a Scar, I can see your atleast on the right track. There is no bad AEG for a beginner. Atleast you didnt want to start off as some CS wanna be sniper. Now as an addendum to my statement that there is no bad AEG for a beginner I would just to add that cost in most cases equals quality.
Now, if your budget is lower, less than 500. Then shootsoft.ca will be somewhere you wish to look.

If your budget is under 1000 then you may wish to consider

Please keep in mind that AA surplus will be discontinuing their airsoft sales as of sometime in march.
Things to keep in mind when initially getting into airsoft.
-Its usually best to start with an AEG, which you have already elected to do so, so kudos to you.
-Remeber to factor in the costs of gear for your kit, BDU's, footwear, vest or holsters, slings and most of all, eye protection. Money can fix teeth, but I dont think we can fix a shot out eye yet.
-You dont always have to have a side arm in the begining, its something you can pick up along the way.
-In most cases its recommended to play with your gun stock for a while before considering upgrades. Upgrading can be costly and can cause complications in some cases.
-Dont forget to buy magazines for whatever gun you choose. High caps are ok, but well they rattle. Mid caps and low caps in my personal opinion are usually the best bet.
