Quoting Smokey_Taboo:" Oh wow I've looked into all those things and my total didnt come close to that cheap Where did you buy your stuff?"
I bought my body refurbished from B&H for 749. My lens from them too for about 150. The 2 umbrella lights I got off ebay new for about 50. My speedlite is a Yongnuo and it was about 150. My Tripod is from ebay as well for 20. The reason I have an extra stand for my flash is b/c when I got my umbrella lights one of the stands had a clamp that was broken so they sent me a whole new stand but then my dad fixed the clamp so I have an extra and my flash will fit on.
A lot of companies will sell things a little cheaper than on their websites or stores and/or have free shipping (which can add up) on ebay. The speedlite is from China lol and I usually don't buy stuff from China especially camera equipment and expensive stuff but I've used them before and they work great. It actually works better than the Nikon SB-600 I have at work IMO.
