I think Jeff is right when he said " It's not the camera that takes a good picture , it's the photographer " .
A person that knows what they are doing can take as good a photo with an inexpensive camera , if not better , than an amateur with $$$$ worth of equipment !
Digital cameras are going to get better , have more features , and cost more , just like everything else . There is always a point where the prices start to drop , but the manufacturers will always find a new feature to justify raising the price again .
Personally , I don't feel taking photos of a model to show on a forum should be about the photography . In fact , there have been some really great photos posted here that don't really show the craftsmanship and skill that went into the build ! A good point and shoot with a close up feature , and proper lighting without a clutterred background works just fine .
