<b>A)</b> The digital rebel is basically the same as the Rebel Ti, saying that you think the digital rebel sucks is saying that you think your own camera sucks. It only sucks for people who utilize the many custom functions, metering, buffer, and AI Servo of the other Canon DSLRs.
<b>B)</b> eastcoastskier got the lens wrong, he was talking about the EF 28-105mm f3.5-4.5 II USM lens, which is the one I have. It IS definitely worth the extra money as it's one of the sharpest Non-L lenses Canon makes. The sigma you're looking at isn't exactly the best lens out there, which is why I think you should get either the EF 28-105mm f4-5.6 III USM, or get my EF 28-105mm II if I decide to sell it.
<b>D)</b> People, this camera was originally owned by Mike La Anyane (Mauii), and then myself, and now Martin. Talk about the village slut camera Lol, I BARELY used that tho so it's still in killer condition.
