I kind of agree with the point Drex made. But not using those words.
When I was 16 I grabbed my moms camera (P&S) and just took photos of whatever, PP'd the sh*t out of them and tried to sell them to make some money, when I was 16 I got a job during the summer and when I was around 17 I bought my D40x. Yes I still have the dam thing. 2 years now with it and I think there's only a couple things I haven't done with it yet. Learn your camera. A wise man on this forum (Kundalini, KMH, Derrel, Bitter, (erose even) tirediron, and bunch others) once told me, "Upgrade only when you feel your current gear is holding you back.
If you felt it was holding you back, try and make some money, sell the camera, and then go buy the new one. I see you did that but came up short.
When you got the offer you saw you were up short so *you* should have declined. Keep saving, you barely have the money for a 60d BODY ONLY. If you sold your lense(s) with it, you now only have a 60D camera body. Still no photos.
Plan it out. You may only be 16 but I bet you're a smart kid.
Hope this helps a little.
