Buying a fish eye lens adaptor?

I have a nikon d3000 and I have seen a few photos that have been taken with a fish eye lens. I can't afford a good one (about $1000) but I've heard fish eye lens adaptors are a bit of fun? I've done a bit of research and have found on ebay that you can get a 0.18x lens
(http://cgi.ebay.com/Zeikos-18x-High-Definition-Fisheye-Lens-Fish-Eye-NEW-/200515731256?pt=Camera_Lenses&hash=item2eafab3f38#ht_7514wt_1137)
Or there's ones with different focal lengths like 0.22x and 0.42x? I'm wondering what to get for the best 'fish eye lens'? Does anyone have any photos they can show me they've taken with the lenses etc?

So what would be the next "step up" for portrait/still life photography in my case, lens-wise?

So I'm thinking of buying a Nikon D5000. They're reasonably priced on eBay (camera shops here retail them for over $1000). I notice the ones sent from Hong Kong are the cheapest (around $400-$600). Would these be the real deal, or a fake version of the camera?
