I finally found it:

For my spectrophotography I wanted to find out what ISO and different values actually mean for picture quality and I found a website that has it!
I am stuck between the Nikon D3200 ~$600 and the Nikon D3100 ~$300. I guess I could test them out and if they don't work well just return them but then I can't buy them off of eBay and eBay saves some money. Well D3100 is like $300 on eBay and about $475 on Amazon! The D3200 is about the same on both unless I troll eBay seriously.
Hmmm tough choice...
