I have been using Intonator since 1998 for on-the-fly pitch correction
and am very happy with it. I have not used Antares Auto-Tune, its lower
cost competitor. The Intonator has superior front panel touch of a
button functionality, which I find very important in studio work, being
able to react quickly, so I rejected the Antares product from the
beginning solely on that basis.

Although you didn't ask, for computer-based pitch correction, I use
little-known but sensationally capable Celemony Melodyne, which costs
$800. I've been using that since early 2002.

Just a point of warning to add to what I said:

No pitch correction product is flawless. You have to always be
listening for artifacts, which can range from inaudible to unacceptable.

Wonderful tool, but you have to be careful.
