Hi,
I have been salting my turkey for a couple of years with really good results. Cook's Illustrated had an article and recipe in December, 1996. (Yes, it is adapted form Zuni's chicken recipe.) It takes some time and care (finger nails will cut the skin) to separate the skin from the breast, thighs, legs and back. Dry brining may be done one or two days in advance. The salt is completely rinsed from under the skin before cooking. This has the advantage of allowing you to place herbs/seasonings under the skin and to lightly salt the skin just before cooking. You can use those expensive ingredients at this point.
The technique allows for a very crisp skin with flavorful and moist meat.
One disadvantage compared to wet brining is the lower moisture content of the breast meat. The dry brining process means faster cooking and the breast meat can over cook before the dark meat is up to temp. Cook's Illustrated's solution is to ice pack the breast inside and out for an hour before cooking.
The turkey (12-14 pds) is cooked breast down for 45 minutes at 425 degrees and breast up at 325 degrees for another 1 to 1 1/2 hours.
This is an excellent way to cook a turkey.
