Recommend 6 foot iPad cable

[Kate]

I'm trying to set up a charging station in the motorhome and I need 2 or 3 six foot cables. I keep seeing that not all cables will work with the iPad 2 and ideally, I'd like them all to charge the iPad as well as the iPhones.

Geez, there's a million out there. Can somebody recommend a reliable cable that hopefully doesn't cost $20?

There's just so many to choose from, i'm hoping for input from actual users.
