My key fob broke years ago and I've just dealt with it, but I'm trying to get the X into better shape than it has been. I saw that I could buy one from courtesy for $95 but found this one on ebay for $15. Anybody used this seller or bought one of their Fobs? Here is the link.

A key fob is a key fob. I have had oem and aftermarket and fell that they are all the same. If you want a Nissan one buy it used off ebay and program it yourself. Directions are all over the net.
