Is this too cheap to be legit?

I found this page on Geek Buyers and the drone seems very, very cheap. I have wanted a cx-20 for a while, I bought myself a Xiomi Yi camera and a Walkera G-2d gimbal, now I need the CX-20. I found it on Gearbest also but for 40$ more (http://www.gearbest.com/rc-quadcopters/pp_113550.html)
Are these models any different?

 

Yes. Regarding the cheaper one.

I'm not a fan of GearBest, I'd buy here:

Thank you. I need a cheap fpv kit (preferably under 60$) to go with the

• Cheerson cx20
• Xiomi yi camera
• Walkera G2d gimbal

I am planning on ordering the cx20 and the gimbal from Banggood so it would be better to be on there.
I need a monitor also. Thanks for your help!

 

thanks for the info....
