The SM58 is a safe bet, but if you're looking for something else, I would recommend trying the Shure SM57, Shure SM87, Rode NTK or Sennheiser 441 (they're all on the cheaper side too) You'd be best off going to a music store and asking to audition their microphones to find one that suits your voice best.
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.
