I think I just sold my soul...

Okay, but there is a saying that you should take on-board. It is "Two is one, and one is none." You have two bodies, but one of everything else. Borrow a spare flash and a back-up lens too. A standard zoom would be good as a back-up. See if you can get a f2.8 lens as well. Even if you leave it locked in the boot of the car, it may save your butt if something breaks. I have dropped cameras and lenses, and had flashes fry on weddings. Stuff happens, but if you're prepared, you can keep going and finish the job. Good luck with your dilemma too.

I've got a few back up lenses that belong to my partner, and a flash that belongs to my parents that I can use as well as my equipment. One of the 400D's is actually his, but he hasn't used it for over a year, so I've pretty much claimed it.

Just had a thought...my parents just bought a 5D MKII to go with their 550D. I should just borrow their gear and rock up with the 5D and 550D!
