I have a buyer for my 50D+grip for 550 USD. I was going to use this money to upgrade my glass or get another strobe. Do you think it's more prudent that I have a back-up body or that I get more glass/supporting bits in my kit? I do a few paid gigs a month as I'm just starting out and I've always been told 'have a back-up' so I've been wary of selling the 50D. However, since buying it I've put maybe forty clicks on the shutter after getting to know how to use it. The 1D3 has given me no grief. I'd like to get a pro's opinion.


so if you can get your buddy's camera as a backup, I'd say, yeah, sell the 50D and get more glass.
