The quality is the same, just that they have extra backlit led. However, do bear in mind that backlit led is just another thing that will spoil easily. It totally depends on your luck. Take for example, CMstorm Rapid-I is notorious for their high led failure rate. Ducky is a little better in this case. You just need to know that the led can fail at any time and it's normal albeit small chance for it to happen. But when it happen, it happens and suddenly one of your keys dont have backlit. Thats why some people prefer non backlit to save $$ and frustration.

can consider mx linears (red/black) which is going to be quieter than mx tactile/clicky. It can literally be quieter than rubberdome keyboard if you type on it softly, else, it will be loud if you bottom out and smash the keys.

Hey guys, so the keys chattering on my ducky board is getting serious. Is it pcb problem or switch problem? Seems to be happening randomly in many of the switches.

Should I rma it or should I replace it?

Not exactly serious. Cause when I spam clicking two switch alternately, like asasasasasas, I can't seem to reproduce it. :/
I will notice it like, once or twice every 1 hour at most. Often have to backspace to delete the extra character..

A filco majestouch is famous for it's quality and solid build. It is TKL, not full size and no LED. It is over your budget and cost about RM400+ Iinm. Also, even if you were to get a filco, if you want white keycaps, you will have to fork out at least another RM100 for white keycaps. Expensive keycaps can go all the way to few hundred bucks and even more expensive than your keyboard.

If you want dual led, can check out ducky, however, they are also out of your budget at a price of Rm500 for a ducky shine 4.

Well, there's always a way. If you really interested in a mechanical keyboard, you can spend less than RM300 to get a basic keyboard with no led. Bear in mind that some keyboards with LED have a high failure rate in the LEDS, the led will die one by one if you're unlucky.
