It kind of depends on how large of a dehydrator you need and how much you want to spend. You might just get a cheaper one to start out with and see if you really like it and want to keep doing it. I have one that was less than $25 and it works fine.
If I was going to get a new one I'd probably go with the Aroma one that is $28. http://www.google.com/search?q=food+dehydrator&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a#q=food+dehydrator&hl=en&client=firefox-a&hs=n5k&rls=org.mozilla:en-US:official&prmd=imvnsr&source=univ&tbm=shop&tbo=u&sa=X&ei=c4mCTrC6F4fZ0QGBhoCBAQ&ved=0CMIBEK0E&bav=on.2,or.r_gc.r_pw.r_cp.&fp=e5de067803ff3d83&biw=1120&bih=507 &fp=e5de067803ff3d83&biw=1120&bih=507.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
