allow me to talk about my camera...
i picked sony because the memory sticks are the cheapest, compared to the prices of compact flash and smart media...

Mister T, remember that you have to spend extra on other things... extra batteries (charger if they are rechargeable), a reader (if necessary), a case for the camera (if necessary), extra memory (which is necessary), uh, um, a slave flash (if necessary, it has been my observation that on-camera flashes suck, and if given a chance for a slave flash, go for it)...
as for money, my sister bought me a sony cybershot 505v, which was $800 online... I SPENT close $600 on accessories... extra memory sticks, extra batteries, a slave flash, lens filters (got a polarizer and a skylight filter)... and i don't even have a tripod of my own, yet...
