The 100-300 zooms over at keh.com are the wrong version. They are the earlier power zoom version. The $59 one is the F version which succeeded the FA version (the only time an F lens replaced an FA lens). The version recommended is the FA 100-300 f4.7-5.8, which succeeded the F version and is a new design. But if you have up to $600 to spend, I can't see any reason not to go for the DA 55-300. It's almost certainly better than any of the old FA/F 100-300s and has more range, better build quality, etc.
