Originally posted by Liney Admittedly I've only bought when I can actually go into the store and test the lens, I take an older body with me and after giving the prospective purchase a good visual check I try it on the body.

Same here. I have picked up a few really good lenses at Cash Converters - my Sigma EX DG 24-60mm (which was mis-labeled and mis-priced accordingly), Tokina 35-300mm KA mount zoom, couple of Pentax normal zooms at $20-30 each, a Sigma 28-90mm like Liney's. Also bits and pieces like filters and a couple of airtight boxes for my filter collection.
I have seen lenses that were totally different from the description, damaged and/or way overpriced, so careful testing is critical, as stated, Always worth a look when I walk or drive past.
