I'm a Canon user:
Canon EOS 400D (Digital Rebel XTi in the US)
18-55 IS
17-40 f/4 L
70-200 f/4 L
50 f/1.8
420EX Speedlite
I also have an old 10D I got a few years ago, but I upgraded to the 400D just before the 450D came out and everyone was dropping prices on the 400D - it was almost too good to miss
. The 10D now sits in the bag, not getting used much. But I might use it with my telescope for astrophotography, as long as I can get the software that supports the 10D.
