Excellent tips Revvy. I had seen your dip tube idea and I got a plastic 90° barbed fitting like this:

It fits perfectly into a drilled stopper and is the perfect height.
I do have 3 questions though-
1. I do notice that when I bottle there is a pocket of air in the spigot due to the change (increase) in cross sectional area from the dip tube to the spigot. I don't get air in the bottling wand as another poster mentioned, but it does appear turbulent in the spipot as the beer moves through it. Any thoughts on this? I saw your suggestion about running sanitizer through it first but wouldn't that have the same issue?
2. Does it matter when you add your priming sugar to the water? i.e. cold or boiling?
3. How much should the priming-sugar-water-mix cool before it comes in contact with the beer?
