Well, I sold my D60 and I have decided to change to Nikon for the next Digital SLR. Since I am taking a break from astronomy, the awesome low light performance of the Canon cameras isn't my top priority anymore. So I am selling off all my Canon accessories. Thanks for looking!
Zenitar 16mm f/2.8 Super Wide Angle Lens for Canon EOS ($100 Shipped)
This lens was a savior for me professionally. It is described as a fisheye lens, but with the 1.6x multiplier common to the Canon digital SLR cameras, it provides an effective focal length of ~26mm. THat means you get a nice wide angle view with very little distortion through the sharpest portion of the lens. Awesome for group portraits. Makes great wide angle shots of the night sky!
$100 shipped in the USA. I prefer paypal but will also take money orders.
