Hi irbyma7297,
Gosh, sorry about all the dramatic life events! Hope all is well with you now.
Your earlier events were, how shall I say, before my time? Actually I might have been trolling the forum in those days

.
In any event as we are both still alive, a forum member adame is selling diy battery kits via ebay or his facebook group. Not the nasty diy batteries of your prior life, but a proper battery that will work!
As far "new skins", I think your out of luck there, but a forum member, robot enthusiast, is awaiting a "new in box" Ugobe!
If this is true (and I truly hope it is not a scam), perhaps these people would have "skins"??
Finding a "donor" Pleo with better skin than your Pleo (and cheap), and yours has a broken neck? Tall order!
If it were me (its not, but there you go), I would get some Gibbs or CRC-5 (food grade if you can find it) to remoisturize the skin (it will take a little color with it, try it on the black mark first).
There are many neck repair videos on the forum.
If you balk attempting it on your own, perhaps one of the US based members might sign up for it!
Cheers!
