that example is fisheye. thats also not a lot of money to work with since i'm assuming you would like digital, but-
camera option 1-
canon 1d mki-$354 very old pro body camera, only 4 megapixels. i have one, its good minus the size restrictions. fine for web/magazine use though

canon 20d- $389 consumer level camera, 8.2 megapixels, getting older now, but still good. i know someone who gets published regularly with one
http://www.adorama.com/US%20%20%20%20364128.htmltokina 10-17 -$499 if you can find it used go for it, hard to find though. standard fisheye for canon crop bodies. although if you are just starting, you probably shouldn't get a fisheye anyway.
http://www.keh.com/Product-Details/1/DC099...7N/DC09/FE.aspxcanon 50mm f/1.8 -$76 standard lens, low f stop, can use it for many things.

so this suggestion ranges from $949-$984 (plus tax)
i prefer telephoto lenses, but you can't afford that and a fisheye. you'll have to choose, they are about the same price. i'm only suggesting canon because that is the system that i know. you can build a similar nikon kit for a similar price.
