Next Big Purchase

I'm not the person who earns quite a bit and just buys whatever. I don't work full-time so income is coming very slowly but progressively. I am quite satisfied with what I do at where I work is not important =) I'll get to the point - I'm really hoping that my next big purchase will be a Canon EOS Rebel XSi or XTi / Nikon D60 or D70. A family friend of mine got into photography as a hobby last summer and I've been nothing but interested. It's quite pricey considering the fact that the lenses themselevs can cost up to $1,000 each depending on what they're designed to do. I'm hoping the body will be $600 or less, and am looking forward to purchase a 200MM lens right off the bat. No, that is not the only lens I want to get - I want an 80MM, 55MM, FishEye and 300MM. I'm predicting it's gonna a few paycheques haha but I really hope it'll be a worthy investment.

Here's the breakdown (not accurate at all!) of how much I'll be willing to spend:
Body (EOS Rebel XSi/D60): $600-$700
Lenses (Fisheye, 200MM/300MM[telephoto], 55MM[wide angle]): $1,400



Yes, I realize it's quite expensive but photography is one cool hobby to get into and you'll never know I could be doing photo shoots and earning money ;)
