Good luck, but as IMR said broken neck or not, don't forget the shipping cost and the cost of a battery is going to be at least $50.00 and up to $70.00 depending on where you buy and where it ships from and the cost of the shipping so total could be $145.00-$155.00 roughly. If your mom is prepared to pay for that total, then go for it and good luck. If the neck is broken, then you can either fix it yourself or find someone who will do it for you. If I was going to pay up to $150.00 or so for a Used Pleo , then I would save the little extra and buy the one NEW that sells for $199.00, comes with two batteries and free shipping, just sounds like a better deal.
