Trying to buy an all around condensor mic. I could spend up to $500 give or take. I am wondering the differences mainly between the Rode nt1, nt1000, ntk. I am also considering Akf c4000, and the c3000. I am a novice but would like the best mic I could afford. Also dont want something that will pick up every little noise in my basement and therefore make my recordings sound bad. What do you think I would be happy with? I hear the nt1 but how much better is the nt1000 and ntk? Thanks for any help.
