Ya..speak to people in this field; particular if any of your friends are photographers..
Sam or Leslie is of great help.. I know them too..However, the decision is yours.
More importantly is to estalish what areas of photography you are into..
There are lots of camera review forums on the Net, but these are just a brief guide to the systems concerned.
YOU MUST know what you are getting into and what you would be doing in the next few years with the stsyem.
Look around and you will see.. I came across someone selling a 3 years D70 with a shutter count of 2800 & another; a D70s of 2 yeras with a shutter count of 1200!!
Whether it is a D200 or D2x; if its for hobby you need to re-evaluate from ground zero..:dunno:
Just my 2 cents worth..
