D.H.
I'm going through the same thing...she's getting close. My 2 1/2 yo girl isn't quite ready, but she too is wanting to be changed after each pee, etc. I already change quite often than most people anyway, but I can tell it's getting quite close.
My boys were already trained by this time, but I guess it's different for my girl here. Just hang in there and don't force the issue. She'll be ready really soon if the incentives that were mentioned don't work.
What I did with my boys were buy a bunch of hot wheel cars and let them choose a new one everytime they went potty. They do have little 97 cent baby dolls at Walmart or get several items at the dollar store.
