Spektrum DX6i and USB cable for Sims

[ted_wears_a_hat]

Hi everyone, this is my first post here so first of all I would like to say ola to everyone at the forum. I am very new to RC heli's after being bitten by the bug when I was in the States recently. After a lot of research I am looking at getting a Blade 400 but also want to get a simulator, as such I am looking for some advice as to which cable I will need to link the Spektrum DX6i to a PC using a USB interface. I have a found a site that appears to sell two different types that work with the DX6i tx but I am not sure what the difference is (apart from $10!).

Any advice would be much appreciated. The speifications are below:
