I bought a CYMA CM030 AEP about 11 years ago. It's light, as it's all plastic and the trigger is not great, generally feels kind of fake.
But I really enjoyed playing with it and it served me well in skirmishes. It doesn't shoot hot and it's best using 0.2g with hop up adjusted. At distances 10-15 metres it shoots just fine.
No need to worry about leaky mags. I even bought a long mag holding around 100 bbs and it was so fun to shoot. It also shoots full auto.
I hadn't used it for 9 years and recently I decided to test it. It worked just fine! Even after so many years of no use, no maintenance at all, the battery was fuctionable, the bbs where shooting straight and has no issues.
