True, I don't trust DragonWar brand either (Gaudy design, nothing impressive about performance).
As for TVS-e Gold, yes it is a good mechanical keyboard with cherry switches and that too at such low price point. But I'm not sure of it as a gaming keyboard, as the main feature that I look for is anti-ghosting. I'm not sure whether TVS-e Gold has anti-ghosting and can detect at max 3 simultaneous key presses.
There are many gaming keyboard options at around ~3k, Asus Cerberus or CM Devastator which are good alternates. But if chicklet style keyboard is not an issue then Razer Deathstalker is the best that I've used. Logitech upgraded G100 into G105 which is good cheap gaming keyboard (but is membrane style).
If mechanical is what you want then TVS-e Gold is the cheapest and worth that you can get. For better mechanical, gaming performance budget needs to be around 7k.
Edit: Just read the review of TVS-e Gold (PS2) and it seems anti-ghosting is an issue with USB or a PS2 connected to USB port via convertor. PS2 version of the keyboard connected on PS2 port supports anti-ghosting.
