I like my Arsenal, though it's the basic fixed-stock gun that I upgraded with some Magpul parts. The factory triangle or solid stock folder is a better way to go IMO.
The Yugos are quite nice as well, and being more of a "commodity" kind of gun invite lots of garage customization. This one has a homemade pistol grip, bar-stock sling mount, and top cover drilled and tapped for a rail, among other aftermarket additions. That's a 60rnd quad stack mag by the way. Works well but needs some lube to function 100%.
