What body and lens would you buy if you had free credit to a store?

Say you had $4000 in store credit for a body and lenses only, what would you purchase and why?

I personally am a total novice but if I had the money I would get a 5D Mk3 or a 7D. Canons because I have access to a few of my dads lenses (24-70mm f/2.8 and a wide angle not sure which). For 5D I would get a Sigma 50mm f/1.4 (and pray it's a good one). I love shooting at night and i usually use available light (it's not that bad in New York though). The full frame and fast lens would make it easier to get great images without lots of noise. I also would love to start filming and from what I've seen the 5D Mk 3 can get some great quality, though it's also mostly skill. If not the 5D I would get a 7D and a 50L for similar reasons but the 7D is pretty durable and with the 50L I would have some weather proofing so I wouldn't have to worry so much about rain and snow. I would also pick up the 24-105mm f/4 because the image stabilization might help a bit with filming. I would love to hear what other people want and what they would use it for!
