Openbox/Skybox F3 or technomate 5402

[I am trying]

I need some help
I quiet like the technomate 5402.
I had a google search and I found Openbox and Skybox F3 cheaper and both has a card sharing
My last question is does technomate 5402 is a lot better than Openbox or Skybox F3 as the technomate is almost 3 times more expensive?
