I have an Olympus E-300 and one 510-E. The E-510 works very well and would be an excellent choice. It has many features not found in cameras like the Nikon D40. Olympus tends to be a better overall value and its market share is growing faster than any other brand. That is a testament to the quality of the business and customer satisfaction. I like the Olympus because they are also smaller and light, so that you get to wear all day. Quality wise, no matter what DSLR you choose, you get high quality images.
