Alright, so I'm a little behind on the latest and greatest cameras. But I'm finally ready to bite the bullet and get myself and SLR. Here's my dilema... I can't seem to choose between the Pentax K-x W. 18-55mm Lens and the Nikon D3000 W. AF-S DX 18-55 VR Any tips, suggestions, experience people would like to share? I'd greatly appreciate it!
