Less than $100sgd you can't get a mechanical keyboard in Singapore context. Only way is to save up a bit more like another $30sgd then you can give yourself more choices.
Corsair K70 (Currently I am using)
- Definitely, one of the most sturdy mechanical keyboard of all. It comes with a red cherry mx and I am loving it.
- However it is way beyond your budget.
CM Storm Rapid Fire Series
- This keyboard has a lot of good reviews, and is selling fast in the market. Haven't tried it, but due to the reviews out there, I highly recommend you to buy this. The pricing is around 129 to 145, depends on which outlet you go to.
- Portable, it is small as it removes the numpad. Good for your daily life commuting from school to offices.

Ducky
- Ducky keyboard has always been up there, no doubt especially for its variety in backlit, however the design are not as fanciful as CM storm and Corsair mechanical keyboards.
If you insist on keeping your budget below 100, get a 2nd hand, or order online or go for a non-mechanical keyboard. For non-mechanical keyboard, I suggest going for the Logitech one, they are durable and very sturdy.
I won't suggest rosewill because of a lot feedback that it does not last.
Cheers!
