Hmmmmm.....I just looked on their site, about $380 for a TM Hi-Capa 5.1? I know of where to get a 4.3 for about $350...so I wouldn't say their prices are THAT bad. However, that site looks way too shady lol. Watches? That totally seems legit.
But, like they said, you should get age verified if you can (yes, this is coming from a guy who isn't, but I'm not 18 yet, so I can't). I can tell you however, you will be able to find much better deals in the classifieds on this forum. By that, I mean stuff you won't be able to find on craigslist or kijiji...
On a side note, I bought a WE Glock 23F Gen 4 (It has a full auto function wtf) for $200 (I think that I paid too much...TA has a G18 with a silencer for just over $200...), and I've put well over 4000 rounds into it the past month. It's stood up well for me, I have yet to hear bad things about it.
