Yeah, but what can be an "active sink"? That's the expression that's new to me...

The Clux is available here in Sweden at a decent price, so buying it and testing connecting it to my G68ADV wouldn't be a major financial concern. But modding it myself is pretty much out of the question - if I don't buy a couple extra for practising... wink But I have a friend that might help me out, to otherwise send the CLUX over to USA for modding will be quite expensive.

About how much would a kit cost, and what is the time-frame (if nothing negative shows up)?
