All you need is one of these:
There's a variety of brands out there, Whirly Pop, Great Northern, Cook'n Home, and others. There are debates over which is the best, but we've found them all to work just fine. Whenever we see them at yardsales, we'll buy them to convert family and friends. New you can find them for under $20, though.
Put in a splash of oil and some popcorn and heat it on the stove while turning the crank, and about three minutes later you'll have six quarts of fresh popcorn. Is that really so much harder than doing it in the microwave?
Once you've made the initial investment, popcorn costs pennies a batch. Far, far less than microwave popcorn. It's more environmentally sound because you can buy the popcorn in bulk and you won't have that popcorn inside a paper back inside a plastic bag inside a box.
Most importantly, it tastes great. Popcorn made this way tastes infinitely better than microwave popcorn. Plus you can choose exactly what to put on it for toppings and how much. You can even add seasonings while it cooks for special treats, like kettle corn.
We usually make popcorn this way a couple times a week. It's a great way to make an evening movie seem like an event. It's also a guilt-free snack.
