I've never brined a turkey and it's always turned out really good.
The two best methods I've used for a turkey in a traditional oven:
1) Use an oven bag. Seems simplistic or like cheating, but the dumb things work. The first excellent turkey I made came from a bag.
2) Make a compound butter out of sage, rosemary, thyme & oregano. Chill the butter into a stick, slice pats off the stick and shove them under the skin. Any leftover butter can go on as baste as it's cooking. You'll have to frequently baste a turkey using this method, but the results are pretty good.
