RE: eBay issure
I just looked at the original ad and I agree with zach. I would have expected to recieve those servos as well. They were clearly in the photo with the other "extr parts". Having said that you can try to persue the issue with e-bay and Pay-Pal. I'd start by sending him one more e-mail saying that if you don't get everything that was included in the auction that you will open a Pay-Pal dispute. If you don't hear from him, open the dispute. Pay-Pal will want to know the details so be sure to keep copies of the auction (both of them), payment records and any/all corospondence with the seller.
I think you deserve to get the servos or at least their value.
Good luck
