What cam would you buy for 800$?
 

So I had a nice Canon EOS 300D.
But I broke it, stupid stuff! :D
So right now I just have my N95 and a Canon Ixus something from my mum.
I always wanted to get a new one (about three, four month now) but there was always something else.
New PC, new shoes, stuff like that.
I don't have all the money yet, well I do but I don't want to spend it now, but I start looking again for a new cam.
I would like to know which one you would take.
Some ideas:
Canon EOS 400D (maybe used)
Canon EOS 350D (used with some extras flash aso.)
Nikon D40
OLYMPUS E-510
Sony Alpha DSLR-A200

PS: Or should I start playing for money at Full Tilt and buy a better cam :D
