Should i save up for another rm 100 then can upgrade to ducky?

This question very much depending on your preference and usage, not us since everyone is different.
If you want full functionality and easy access from numpad, get a full size.
If your table is small or u just want something small and probably easier to carry around, get compact size like TK, TKL or 60% layout.

I'm start to wondering about the numpad? I mean buying separately.
Consider me got a tkl, later want to buy a numpad with mechanical switch.

Yes u can get it separately, there's mechanical numpad with mx switches.
So far from taobao i saw is leopold and keycool brand.
Can't remember how much it cost, still quite expensive iinm.

Indeed. Very expensive, maybe the price represent the quality of it.
I found the leopold.

Here's one from keycool, http://item.taobao.com/item.htm?spm=a230r....&id=21861795154
Only mx blue, while leopold one can pick switch u want.

Edit: leopold seems no mx brown and black. Anyway, still can mod it to any switch u like by desoldering and soldering.

Nice yet affordable. The only bad is the keycool have the brand name so big on the numpad
Will see if local have before purchase from taobao.

Anyone in this forum bought numpad separately?

someone might be buying some crazily expensive numpad with alu case and bottom led in near future

Who? Abang kastam? light saber built-in, with alu alloy case..
gulp.. what's the price ?

raindrop is dcs profile, u will have weird feeling to type on a kb with mixed keycaps profile .
filco stock keycaps still not bad.

Thanks for telling me.. I tot is cherry..
So, have to buy dcs profile blank set pbt... Sounds expensive dcs..

Heard that, filco stock keycaps is good also. =.=

edit: taobao no dcs keycaps? macam can't find

Mostly on taobao are oem profile, unless it stated cherry or other profile.
You can find the dcs blank from SP (signature plastic).
