Phidgets Motor Control HC USB Dual 14A 6V-15V Moto

[Mononeurone]

Hi,

I'm a rookie one in sim world and I'm looking for build my own.
Along my search, I found a USB dual motors controller who is looking good to replace dual Pololu JRK or Sabertooth + Velleman K8055 + Velleman K8056.
Because I need dual Polulu, it cost 99 $ piece, so 200 $ or Sabertooth + 2 Velleman costs 180 $.
So Phidgets Motor Control HC USB Dual 14A 6V-15V costs only 116 $. http://www.robotshop.com/phidgets-1064-phidgetmotorcontrol-hc-2.html.
What is your opinion about it ?

Thanks for your answers.
