I'm looking for an AK and I have found two options. I need some advice though soon on the pros and cons of each. My first option is the E&l- it's called a Spartan aks74u however it has E&L gen 1.5. I'm not sure what the whole 1.5 means and how it is overall, but how is this gun overall? http://www.airsoftatlanta.com/Spartan-E-L-AKS-74UN-AEG-p/120954.htm My second option is a cyma CM045. I have seen a lot of reviews of this and how it is a "good bang for the buck." How does the internals compare to the Spartan e&l? I need some advice on these or any other options around the same price range. If I get the cyma I can get more gear, but for $40 more I can get the E&L so I wanna know if it is worth it to get the upgrade.
