Possible Lens....

I have been wanting a new lens for a while now, and Im trying to decide which one to get.  I don't have a TON of money to spend right now, but I am still interested in making some sort of purchase!  I did some research, and I came across the Nikon 50mm lens with a 1.8 aperture!  I found it on best buys website, and it is actually on sale right now for $125!  Yes!!!  This lens is a great buy, and I feel like its a good lens to have in a collection.  Its great to use for portraits as well!  I have two photo shoots lines up next week, so HOPEFULLY I will have a new lens! ;)
