Super easy, super good. Best cooked on the barbecue, but at this time of year in the UK, the oven is probably a better bet. This is the best all round, guaranteed to be liked by everyone, marinade I have found: sticky, a bit sweet, but not too cloying. I think it tastes like it could be a home made marinade but without any hassle and under £2 a bottle.

Chicken drumsticks
Sainsburys Taste the Difference BBQ & Brown Ale marinade (one bottle is sufficient for 20-30 drumsticks)

Put the drumsticks into a large bowl or – even easier and less messy – a large strong freezer bag. Cover in marinade and stir or shake to ensure all pieces are covered. Leave in the fridge overnight. Remove from the fridge 30 mins before cooking. Preheat oven to 180 degrees. Tip drumsticks into a large oven proof dish or tin – ideally big enough to cook the drumsticks in a single layer. Cook, uncovered, for about 25 mins, basting and turning at least once. Either serve immediately, or leave to cool completely before putting in the fridge.
