LOL G15's successor early come out already. G510... BTW, not sure if it is a good board apart from 2 major bad heard from reviews:
The rubber dome down there having some problem and some keys need to be pressed forcefully to register.
The backlit is quite dim.

if u're not going for mechanical keyboards, 250 should be fine.

-microsoft sidewinderX4 around 200+-
-razer arctosa (:S) less than 200
-steelseries ZBoard around 160 or less from Edifier Steelseries stock clearence
-Logitech G110
-ROCCAT Arvo

these should be the ones available in malaysia

I'm sorry to tell you that Mechanical Keyboard doesn't have Macro functions.

Well, they do have, Gigabyte and Razer, These have Macro functions, but for your budget, each of the keyboard is RM280 above, which i don't think you can get with RM250 budget.

For Macros, I'm also a macro user, but i only use macros on the mouse and use a mechanical keyboard instead. so all my macros are relying on my mouse, my keyboard is for NKRO function because of FPS game. but i do play MMORPG, and RTS and other genre of the game, it's just that, sometimes, FPS games, you need to duck, see score, report, reload and jump. that is rare occasion. but when you do it one day with non NKRO keyboard, just hope you won't meet a enemy while you're doing so.
