Used Camera Equipment Wanted

I am in search of used camera equipment, specifically I am looking for any of the following:

1. Canon EOS Auto Focus Lenses (300+ fixed focal length)
2. Canon EOS Auto Focus Lenses (< 28mm)
3. Any Mamiya Sekor Lenses (45mm and 150mm are a definite need)

I would be interested in any darkroom equipment, enlargers, lenses, lightboxes, developing equipment, etc.

Please send me an email and pictures, if possible, of what you have and what you would be willing to take for them.
