Did a little research and found out that you have to spend $2499 on a canon DSLR to get better image quality, and color depth than the K-X... yet the K-X will still have better dynamic range.
The $1699 Canon EOS 7D has lesser image quality, color depth and dynamic range than the Pentax K-X kit I bought for $439!
The $2499 Canon EOS 5D mark II has better image quality and color depth (but not but leaps and bounds) yet it has .6 f stops less dynamic range!
Of course I am only comparing those three things--image quality, color depth and dynamic range; I realize the K-X is lacking in a lot of areas the High End Canons aren't
But image quality, color depth and dynamic range are the most important to me--an amateur photographer that doesn't shoot sports, doesn't need weather sealing and doesn't need all the other fancy stuff.
I'm really happy with my K-X! It demolishes the entry level Canons (for my needs).
