Get a chapalang(or more famous brand like Logi/MS) wireless keyboard and steal their wireless adapter and processing unit.
You should be able to find a more detailed example in GH.

A picture is worth a lot of words.

RM300 or less probably can't get any decent Mech KB.
Most mech keyboard below RM300 is either not full layout(TKL, mini 60%), not 1st hand, not Cherry MX switch or not of decent/top-notch quality(brand).

BTW, if you insist on the budget,
Razer BW Expert(not really recommended except you are extremely tight on budget or you want to do some modding in future).
KBC Poker, some google will tell you fully what it is.
Ducky 10XX series from global.PChome(also not the best choice)
China brand such as Noppoo, Rapoo, PLU, Flashget, Keycool and many more.

Blue LED will be less painful at midnight.

lol, it's just to make way for the upcoming FC700 model, we can't just putting both product in the same price tag. This is one of the reasons why i skipped bringing in FC200R model.
And if you buy the keyboard at the original price 125000 won, and next week, FC700 release, FUUUUUUUUUUUUUUUUUUuuuuuuuuuuuuuuu, more damage on wallet.
Plus, if you look at the main page, http://www.leopold.co.kr/
they did announce the news of new tenkeyless keyboard is going to be release together with FC200 keyboard price drop.
New Tenkeyless Keyboard uses PBT Keycap, Thickness of 1.3mm(new record of thickness? i'll measure them when i receive them), available in Black or White color.

Plus They are highly identical with each other with minor design changed, and add some featu-. ops,  i'll check it myself first.  

anyway, not much people know FC700 will be out soon.

well, myself is O2jammer, and I'm get stuck with 1 song call "dragon rave" and almost passed it, but i need mechanical keyboard which is black axle inside, which black axle keyboard recommend? any o2jammer around?

Jenkwok @@ that's some classic player man.

But black for o2jam... i feel like crying if i'm going to spam Go Berzerk on it LOL

The bloody space bar spoiled

The best chance is to get something like this. A 2piece design translucent keycap. Transparent stem(and font) doubleshot into black ABS.

Thanks everyone and I will post a photo of the broken space bar on my Black Widow Ultimate to see if it's salvageable As for now, I just bought a Filco Majestouch (Metallic Blue case, brown switch) from Low Yat. Initially I wanted the Ducky 9008 with back lit but it's not so solid and nice to type compared to the Filco. The distributor is also not very friendly it seems so I'm particularly worried about the after sales/warranty. I don't mind either because price is not an issue.

hmmm between ducky 9008 shine and rosewill rk-9000 which is better?

just got my self a ducky shine today 

owh and its my 1st mech and backlit kb 

argg, i hand gatal liao, bila my FC700 terbang mari aaaaaaaaa

modernopc at subang for 389 blue switches

Well then good thing I'm considering buying another one then =P

Right now I'm just torn between getting either a Red or Brown(probably Leopold since Cyclone selling it). I keep reading about how Reds are too soft thus can cause inaccuracy which worries me since I play SC2 quite a bit.
