[moved] Recomendations for single board computer for IoT gateway project

I am looking for an ARM single board computer for my IoT gateway project, who can recommend me one which could meet my requirements as below?
Low power
dual Ethernet
WIFI
bluetooth
OS Linux
low price
lifetime above ten years

I had a look at an item from Forlinx Embedded Tech. Co., Ltd and its name is i.MX6UL, its details are as below

I'm now hesitating whether to buy it or not.
I want to buy it because of its low price (a single board computer i.MX6UL with 4.3'' resistive LCD promotion price is only $62), but what made me hesitate is that its carrier board is a little big because I want to find a complete board to be used in my project but do not want to design a new base board by myself.
Who can give me some suggestion.
Thank you so much for your kindly help in advance.
