Whatever you do, make sure you score the skin on the breast before cooking - it helps let some of that excess fat run out, making for a more healthful, and palatable, dish. Hold your knife blade almost parallel to the skin and make shallow slashes with it - don't cut through the skin, just sort of nick it.
In america, a cheap bottle of red wine is only around five bucks. I generally drink wine that is no more than 15 bucks. The average good quality wine is like 40-50 bucks, high quality being 80-100 bucks, with no real upper limit. I would think that britain would have easier access to the table wines of europe.

This also helps to make the skin more crispy, beautiful taste.
