Which is the best Digital SLR Camera for a beginner?

One that fits within your budget.

Whether you are a beginner or a pro, all cameras operate the same.

Visit a camera store and hold a few different brands in your hands and see which fit the best.

Brands? Nikon, Canon, Pentax and Sony are all good systems. Which you choose will have more to do with matching the system to the type photos you tend to shoot.

Here is what I found on the JD Power website

Single-Lens Reflex Segment – JD Power
For a third consecutive year, Nikon ranks highest in the segment, achieving an overall satisfaction score of 711 on a 1,000-point scale. Nikon performs particularly well in picture quality. Canon and Pentax tie to follow Nikon in the segment, each receiving a score of 697. Canon performs particularly well in functions/performance while Pentax performs well in operability

Nikon D3000 is a good camera for beginner. It is easy to use with nikon Guide Mode and take good picture quality.
