As much as I love my Leicas, I did go with DSLR's for most of my wedding work. D100's and D2h's, soon to have a D2x. I do like the Epson, but not the price for 6mp. The D2x is getting great reviews, if you are a Canon user the 20D and 1D Mk II are excellent performers.
IMHO, Nikon has the iTTL flash system down better than others, which flash is a must sometimes.
Downside is if you are used to RF's, these DSLR's get heavy. I'm starting to be able to keep lenses to a minimum, just using the 17-55/2.8, 85/1.8, and 80-200/2.8.
