Equipment For Recording - A Buying List

["too_many_tools" too_many_tools]

I am just beginning to record nature sounds....but I have a strong in 
this subject.

Since I am beginning, I have little preexisting equipment.

So for someone who is beginning, what would you suggest for equipment?

I would like to have it grouped in a low cost, medium cost and high 
cost grouping so I can decide how to approach these acquistions.

Also other than the obvious microphone and recording device, what 
other equipment comes to mind that you would recommend?

Also any recommended sources would be appreciated.

Thanks
