Comapre ADSL Modem

Hi
What is different between these ADSL Modems? Wich is better?

ASUS DSL-N14U
ASUS DSL-N14U-C1

What is 'C1'?

As far as I can find out, that C1 refers to hardware version.

Downside on that, neither Asus' own site or any others seem to know it exists and I base the hardware version thing on the fact that other Asus dsl modems/routers have had similar hardware upgrade add-on to end, either B1 or C1 and so on.
N12U has had B1 and C1
N12E has had C1
N10 has had B1 and C1

So.. since Asus doesn't know that N14U C1 exists, I doubt it's existence? If it would exist, it would likely have slightly better hardware. (N12 had upgrades to onboard ram and firewall/port forwarding)
