Hi! Im a newbie around here, I would appreciate some suggestions on a lens. I just bought a Canon G9, Im looking for a zoom lens, something good but Im by no means a pro, so Im not looking to spend an arm and a leg on one! Think I could get anything good for around $75.00(Maybe on Ebay)?? Im pretty clueless(its not that obvious, it is?:blushing about lenses. Thanks in advance!
