Both pc-cable.com and pocketmapstore (
http://store.yahoo.com/pocketmapstor...ca4rofor1.html)
have cables for under $ 40 -- but no power for either unit. Netsupply.com has one with power for both at $60. I know I saw one somewhere with power like netsupply's for way less . I'll post when I find it again.
cheers,
