Paul,
A GREAT find, enjoy.
I have used Stephen's folks with my S2, sent it there directly from an EvilBay seller and it came to me smooth ready to shoot.
As you live in the Sun Shine State there is a guy down that way, Peter Smith who is to Nikons like DAG or Sherry is to Leicas (one of the best).
Do a search here or on the net and you should find some info.
On the topic of buying the camera for too little, bunk. You did the right thing. Now what you might do is go back and purchase some more stuff and drop it buy Good Will. Or perhaps go back and take a picture of her with the S2 and give her a print.
I too sell stuff for much less than it's worth, it's good to see stuff I've enjoyed find a good home that will love it as much as I did.
B2
