I had trouble first at seeing his photo and saw the descripton that said, Tail split but can be glued, but then the photo did show up and it looks like split skin on his neck also, For the price he is asking it is rediculous and I am sure those batteries unless just purchased are also no longer good as he said, Pleo damage due to dryness I think, from being stored and where you live is hot and dry, yes or am I wrong? anyway, for that price unless Pleos are very very rare, you may as well forget it! Kat bought one from me in better conditon and even with shipping did not come to that price and the new $199.00 Pleo on ebay has free shiipping so that is a deal.
Now to answer your question, well in this condition if you just want to try and fix Lilo's neck and use the skin on the other one in the condition it is in, minus the batteries that must not work, he need not even send them in my opinion, I have bought similiar ones here in the U.S . for $100.00 or less. I have bought one that only cost $80.00 and nothing wrong with it, very very minor rubs, so that is all I can say, You must decide how bad you want this, but I would think $125.00 plus the cost of shipping is all I would pay, and I would want more closeups of that neck skin and other, then you can negotiate price down better. ( to your advantage.) If you ever get it and find out how to fix the broken neck, please let me know. Oh, and by the way , how often do Pleos break their side neck cable where the neck can only bend to one direction and still goes up or down?

Thanks,
Good luck IMR.
