I am easily smitten with Canon EOS 5D Mark II (google product search). But maybe it would pay of to wait for the Mark III?
Currently I use this equipment and I am extremely satisfied. I know the saying „A poor craftsman always blames his tools.“ but on the other hand we all know the tools changed in the past decade and good new technological tools perform extremely well. Just try to upload a 4 MB image on C-64.
