There is a big diff between the classic and the classic 2. Personally I would not spend 1000 on a two. The later Rode models are not as good as the old stuff. I would still prefer the K2. To be honest I think the mic you already have is pretty good for your purposes. I think you need to spend more time and possible cash on the other side of recording techniques like editing and mixing. Spend your cash on protools or Cubase and learn how to use them...then worry about the best mic to use. Perfecting that area will get the best out of what you have rather than wasting money on great mics but not being able to get the best from them.
