Nikon makes white/grey lenses as well.
So anyways, you're wanting something around the price range of the D50? Look at the RebelXti and the D70. You might like either one. Dont base your wants and needs on bandwagon reviews. Most people are die hard Canon and will be till the day they die, and same for Nikon users. Both companies make excellent hardware and glass. The DSLR jump isnt for every person though. Remember even after you buy a kit for 800 or so dollars you still will eventually need more lenses in the future. A lot of high end point end shoots can cover a nice range that a DSLR cant out of the box with a kit lens.
But I will say this, Nikon has over 40 years of lenses that CAN STILL BE USED on their digital platforms. Cant say the same for Canon.
