me too. imo, i dont think there is a huge difference but im not sure coz i never use any mechanical keyboard before. like my G15v2 i use it for massive typing and i feel superb. i wonder what's the difference if i were to use 7G. i cant really afford 7G though. its way too expensive for me to spend on a KB plus, it doesnt have any extra feature.
i bought it for RM255 though. that was like a month back. imo, just wait for G19

i really got poison when i saw that keyboard over youtube

welcomez,
haha, cos it is really a different keyboard with multiple colour backlight... and colour lcd screen and 2.0 usb powered... so the price is quite pricey, but that is pre-sale price, so dunno what the real price yet...

since ur budget is RM 300, u may consider, lycosa, g15v2, X6... i guess this 3 shud be nice, and choose the 1 that meet ur own preferences and requirement towards the keyboard... good luck... 

If you ask me 'too durable' is not a good thing, atleast for me. Coz i will not have excuse to change my KB so frequent la.
