Liz,
you can get the 17-55 IS from KEH in Like New condition for around $919 and on the Buy & Sell portion of the Fred Miranda Forum for around $900.

Heck, right now you can get a U.S. Warranty 17-55mm f/2.8 IS lens for $929 from Adorama and there is some sort of a rebat on top of that! Why buy used?

If you can afford it and if you think that you will stay with the 1.6x format; the 17-55mm f/2.8 IS lens is a great piece of glass. I love it in combination with my 70-200mm f/4L IS lens. Those two lenses fit together very well. I never notice that I am missing the 55-70mm focal range.
