Hi all, Ok, so i'm still comparing these kits and it looks like that first 'quick install' one I was looking at has a "lithium polymer" version:

I'm now leaning towards a front-wheel kit for the reasons Ecowheelz noted above, and having 'easy' and 'lithium' is sounding like a good combo.
Also, like extrajack's story, for me I think U.S. support would really be a big difference from sending stuff all the way back to China if there was some maintenance issue. Thinking thinking...
