Suggestions on my next keyboard?

[check009]

Hi, all!

First of all, greetings from Singapore! Hope I'll be able to contribute to the forum in my limited capacity.

I'd like to hear your suggestions on the possible options I could consider for my next mechanical keyboard.
Currently, I am using Filco Majestouch Ninja Tenkeyless, which I've been using for about a month after moving from CM Storm.

Below are some requirements I have for my next keyboard:

• Budget: Approx US$100+
• Switches: Cherry MX Red/Brown
• Numpad! - Unexpected need for full sized keyboard for work
• Must be ergonomic - CM Storm Ultimate felt too tall and my wrists were bent unnaturally
• Low profile design preferred

Thanks for reading! Hope you can share your wisdom with me haha.

Cherry MX Board?

I can't tell what the prices are like in Singapore.  The 6.0 may be out of the price range while the 3.0 might fit.  Both have low key caps, so I suppose they could fall under "low profile".

Does it have to be a new one, or is used ok, too?
