For me the secret to a good turkey, regardless of the type of oven, is as follows:
Thaw bird thoroughly. Dry it inside and out. Liberally coat the outside of the turkey with good quality vegetable oil (peanut oil works well).
Do not stuff the turkey. But I usually put some strong herbs in the cavity, like fresh rosemary, sage, oregano. Maybe some hot peppers (like Serrano) and some crushed garlic as well.
Preheat oven to 450F. Put the turkey in the roasting pan (shallow) on a rack upside down. Place in hot oven, allow high heat to sear the outside of the bird for 15 to 30 minutes.
Lower heat to 325F, cook according to chart (generally 15 minutes per pound for smaller birds). 30 minutes before scheduled done time, turn bird over to brown breast side.
The reason for putting the bird in upside down first is twofold: one, it allows the fattier dark meat to self-baste the drier white meat for most of the cook time. Two, the dark meat requires longer cooking and the higher it is in the oven the more it will cook.
I generally cook it until the breast meat is at least 165F and/or the dark meat 175F.
All that said, I usually don't use a conventional oven for this. I usually use an outdoor covered BBQ. For the charcoal fired BBQ, I place the bird upside down as described and use plenty of natural fruit wood to gently smoke it. After the initial sear, the roasting temp ranges between 275 and 325. Sometimes towards the end I'll just let the coals die down naturally, which gives the meat a nice "finish".
If I'm not up to tending a live fire, I'll use a covered gas fired BBQ/Rotisserie. The one I have can handle up to a 15 lb bird. After the initial sear I'll usually put a drip pan with about 1/2 inch or more of water in it. The rotisserie burner does most of the work, but sometimes I'll put one of the side burners on low to maintain 300F.
I never need to "baste" the turkeys, because the oil rub and the initial searing holds in the juices, and the slow roasting temp means it won't dry out.
Here's a photo taken just a few minutes ago of the 15 lb bird on the rotisserie, after about 15 minutes of searing at 450F.
