I bought my first DSLR last November: Canon Rebel XSi (aka 450D), the latest in their line of entry-level DSLRs. This model improves many shortcomings of the earlier versions (XTi, XT). The picture quality is outstanding, though I wish I could afford one of their high-end “L-Series” lenses. (someday…)
I was torn between this model and the Nikon D90. In the end, I chose to save money with the Canon. I’m very happy with the camera – excellent photo quality, good blend of features and ease-of-use, and enough performance to keep up with an active 6-year-old son.
Mine came with a “kit” zoom lens. I added a 50mm Prime (non-zoom) lens, a more powerful flash unit (430EX-II), and a set of adapters to use my telescope as a 1800mm lens.
At this point, I’ve spent close to $1000 US, so I guess I can’t call it an entry-level purchase. The true entry-level models would be the Canon Rebel XS and either the Nikon D40 or D60.
I can recommend the site http://dpreview.com for reviews, though it is somewhat technical.
