Ok, I want to upgrade my current Canon DSLR - it is a entry level model, a few years old and am lusting after something a little faster, IS lenses (preferably faster than my current lenses) and something with a self cleaning sensor.

Should I stick with Canon or save more $$ and go for a Nikon?

Professionals - what equipment do you use and what would you recommend?

TIA

(Note to self: All depends on whether DH gets a bonus this year - otherwise keep lusting)
