EDIT: thanks nthfinity for editing the link
yeah, they've got just this model, 'cos A85 is the previous model, so you can buy it second hand
but I think this A95 is excellent and I would buy it, if was starting using digi cam
... just to make you sure: you can NOT change the lenses on the "cheaper" cameras
I had a chance to work with this camera just one day, but the quality of the pics is excellent (well, it's canon, you can't expect anything else...)
