That also got very high reviews on amazon. It should be good.
Thanks.

extender cables...
I received the Juice cable yesterday I've done a little more experimenting.
Neither cable works reliably for syncing the iPad through any of my three USB hubs. There just isn't enough voltage after the cable resistance v drop to keep the iPad charging so the iPad 'acts funny', i.e. it continuously gives the beep and acts as if the cable is being connected/disconnected. iTunes does not see a device or gets an error when reading the iPad. This is when connected to a 500ma USB hub port through either extender cable. Both cables work as advertised when connected to my 3GS iPhone via any of the hubs, but then the iPhone has a much lower current draw so the voltage drop won't be nearly as much.
Both cables work as advertised when connected directly to a USB port on my iMac. These ports offer a bit higher current and the iPad doesn't give the 'Not Charging' indication.
From this I gather that the iPad current draw is on the ragged edge when connected to a 500ma USB port. A reduction in voltage through a longer cable run may produce the connect/disconnect cycle I have observed.
The 3Gjuice cable works fine for audio--I tested it with my iPhone FM adapter--no problems at all. The FM adapter has more charging capability so the iPad doesn't act funny. That would be the caveat--does the iHome or whichever system is used provide enough current to keep the iPad from thinking the cable is constantly being plugged/unplugged?
