Are you looking for something with or without warranty? You can pick up a nice used camera like I did anywhere from $600 and up. I got a 6.3MP Canon 300D and I love it. It's perfect for me. It has the features I need for a beginner. And since I already had a 35mm Canon SLR both of the lenses work with the digital one. It's a bonus!
Like people said tho, you'd probably be better of going with Canon or Nikon. It's kind of like debating if you should get a fully loaded Cavalier or a basic Civic - both same price (more less) but which one will be better in the long run? (no offence to Cavalier drivers :P )
Good luck with your decision!
