Hey all,
A method I use at home is to record 3-4 vocal tracks one after another and then slice and dice the best parts together to make a single track. Most times pitch is not a problem for me because I know well my own limitations vocally. Having said that, when I work with other people and they can't be available for a redux I will correct minor flaws using pitch and time controls in my old cool edit pro program. Used too much it will produce artifacts that can ruin a vocal such as out of phase sounds and tonal changes. I agree with the consensus here that melodyne and autotune are valuable tools but I liken it to using a sledge hammer on brad nails. Hit it as softly as you can.

Ps. The most abused tool there is is reverb. Reverb has ruined more vocals than anything else.
