Which keyboard should I buy?

[Max_Styker]

I have the Razer black widow 2014
But I want more than just green colors. Should I buy the Redragon k551 or k556?
Budget is 50 max rgb and mechanical.

I didn't know they made mechanical RGB keyboards that cheap. Are they any good? That's what I would be asking. Personally, I wouldn't downgrade in quality just to get RGB.
