Canon DSLR shooters should be familiar with the L Series Canon 24-105mm F/4L with Image Stabilization. It's one of the best all around general lenses to take when you have to move fast, zoom in/out, maintain a solid aperture, and have image stabilization. Typically the lens sells for more than $1K, but this eBay seller is selling at just $682 US.

Typically when you see these prices it's still a brand new lens, USA version, but came from a Bundle (minus camera body), and they've used up some type of rebate. So what you'll end up with is a nice new lens, but not in the original retail package. Still a great deal if you want to go this route. Check it out on the product page (here)
