Having what I feel to be a minimal singing voice yet trying to be emotive, a high class mic is not the answer to me.
I have a recording I did with a singers mic, and I have a retake of that recording I did with a 7 dollar headphone chat mic.
No one could really tell the difference between the 2.
I go from instrument or instrument to analog recording device to computer.
But I know from hearing acts like The Buggles or Level 42 that the vocals may not have been superb, but they had a style.
And they most likely did'nt sing on anything less than a singers mic either.

The best bet for a singers mic for me so far has been the Radio Shack Super Cardoid singers mic.
There is'nt all the bad effects picked up with it, but it will diminish the sound too and is quite noticable when plugged into a simple sound card than from my non-singing mic.
When I advance with my recordings, there may be a need for my actual singers mic.

But if you are looking for something to enhance more than what you naturally have, you should'nt go there if you want to be original, and pick a basic mic you can plug in and go for the emotive quality of a basic line-in mic.

But that all depends on what you are after with your sound.
