Thinking of getting a battery grip for my D300. Anyone have one and if so how do they find it.

Silly question but what are hoping to get out of having one? If it's simply battery longevity why not just buy a spare battery and put the rest to that 70 - 200 mm lens you're thinking of getting?
Maybr I'm not taxing my D300 enough but the one battery seems to last ages for me![]()
If you just want the extra battery life out of a grip, there is a 3rd party manufacturer that offers a grip with a dedicated Li-ion battery. Supposed to give 5000 shots from a Canon 40D, and I think the info I read said they had loads of types for other DSLR's. I can't find it on a quick google but I have a link at home which i'll post later.
