Well I've owned a TM AK-47, and I can say that it probably is one of the most solid guns out of the box that I've seen.
I currently own a TM G3-SG1 and I love it, but I've had to invest at least once more the value of the gun to get it to be a competitive field gun. ~$200-250 for a FMU upgrade, metal body and metal cocking tube to get rid of the horrible squeaking sounds and just reinforce the gun. ~$150-200 for a plethora of internal upgrades, and ~$150-200 more for a decent scope with mounts and stuff.
So I guess as far as out of the box criteria, it's not that great, but this and any other gun can be fixed with more money put into it
Also, it's quite big, so it's much better for larger outdoor games, not very good at all for CQB.
Conclusion: Probably not the best newbie gun.
I have to say I'm kind of skeptical about this thread, I think what will end up happening is people coming in here, seeing their gun be trashed by someone, and write their own review to defend it. Greylocks or someone should possibly incorporate important posts and stuff into the main post to make it a little more official.
