I brought mine when it first came out in Hong Kong, 5d3 with 24-105 kit for around US$4400.
No regrets, I took it on our honeymoon a week later.
It replaced my 40D kit set.
the only pain now is I'm spending $$$$ buying more lens and accessories.
70-200 f4 IS (amazed)
remote transceivers for shutter and remote flash
430EX flash (from friend)
ND filters and attachments
1.4x extender Kenko
3 camera bags (1 for travelling, 1 sling bag everyday use, 1 shoulder bag for 5d3&50mm 1.4)
