I almost always use the oven method. Bottling is a big enough ball pain without having also to sanitize the bottles on the same day. My method (from John Palmer), which has never failed in the years I've been brewing:
Remove labels and glue. That stuff stinks if it's cooked!
Aluminium foil to cover the opening of each bottle. Place bottles in a cool oven. Set oven to bake @ 310F, let bake for 2 hours (that's two hours AFTER temp has been reached, not two hours after you start the oven). At the end of the baking time turn the oven off and let the bottles cool on their own, preferably overnight. Remove, sort, store. As long as the foil remains intact, they're good in perpetuity.
