Sometimes 700-800 is alot of money for some people, i know it is for me.

Full-frame is great but just like everyone else says you need only EF lenses, and so forth. Personally, i'd learn to use your t1i first as much as you can. It's a great camera and you will get awesome images from it. Full-Frame isn't going to make you a better photographer, its just a "nicer" tool for the job. I'm using a cropper, and have many awesome images that make me very happy!
