Help me make a quick decision PLEASE!!

This is my fist post here and I reallly need some help....

OK I have a a tough decision to make. Its time for a second primary camera. I have looked at the 5D, 40D and 50D. I have a real paying wedding at the end of the month and my 30D has a shutter button that needs to be fixed. I am really thinking about trading it in and getting 2 of whatever I choose....Just a thought right now. I f I go with the (1 all I can afford) 5d my chances of getting my 70-200 are shot and I have to get my 30d repaired. Would it be worth it and keep renting lenses and have a full frame camera?? Hmmmmm!!! I really wish all the cameras were on the table I don't think the 50D will be out until mid October and that doesn't help my situation.

Welcome! How do you like the 30D? If it is right for you, get it repaired and/or get a refurbished 30D.

So realistically your choices are
1. the 5D
2. the 40D and the 70-200
Not knowing anything else about your situation I’d go camera and lens.

easier solution, rent two 5d, 70-200, 24-70, two 580ex. it'll come in around 400, maybe a bit more for half a week to a week, but then you have it covered regardless of what happens to the 30d

If it's a wedding, paying job or not, you'll need two of everything at least. Equipment failure is inexcusable.

Basroil's advice looks good to me.
