Welcome to APF Fishtk75!
In response to your question, my first question to you is if you are versed in photography or if you have been tinkering for a while in the digital world. If so, you may want to check out DPreview at the link below to preview all the cameras out from the biggest manufacturers to find the one with the features and price that you like. If you don't feel like you know exactly what you want, or what kind of equipment requirements your style/s of photography will have, I highly encourage you to purchase a formal book on photography. This one-time purchase will prepare you for purchase and will ENSURE that you spend your hard-earned money as efficiently as possible. With the kind of money we throw around at cameras today, a day's worth of study can make or break your purchase involving large sums of money. That, and it's nice to know you bought exactly what you wanted, for a good price ;-)

With all this said, one can pick up a nice "pro-sumer" (6-8 mp) camera for around $650 these days, with used cameras running even lower in some instances. Sure, these cameras are not interchangable-lens DSLR cameras, but they can take very nice pictures and can be used for backup once you progress to a level of photography requiring a DSLR.
Places you can buy these cameras are everywhere, but the best prices will be found in photography magazines where the competition is the stiffest, and of course, on Ebay, but beware of sketchy sellers (ALWAYS check their feedback).
With all this said, I apologize if I just told you everything you already know, but, good luck finding a camera, and I look forward to seeing your pictures in the future!!!
