I think if you're used to super-salty, super-yellow microwave popcorn, you're going to find that stovetop or air-popped popcorn isn't your thing -- at least at first. It's definitely a different taste and texture. Practically a whole different food group, IMO.

That being said, I have acquired a real taste for homemade! I have a whirley pop stovetop popper and I think it makes the best popcorn ever, but I wouldn't run right out and buy one until you know that you're really going to make the switch from micro.
You can use a butter flavored popcorn oil for popping, butter flavored cooking spray to get more even coverage, flavored popcorn salt, etc -- but to me, this just adds all the junk that's on micro popcorn -- exactly the stuff I'm trying to get away from by making my own. I'm a real-butter-and-salt girl.
The trick to not getting soggy popcorn when you pour melted butter over it is to
wait at least two minutes after popping -- it lets the popcorn cool and crisp up a little. Then drizzle the melted butter slloooooowwwllly over the popcorn...stop, salt, toss to coat...drizzle a little more butter...stop, salt, toss...repeat. If you just dump a bunch of melted butter on hot popcorn, you'll end up with shrivelly greasy kernels and a whole bunch of unbuttered popcorn that the salt won't stick to.
Even at that, you'll never get that perfect coating of butter and salt on every piece like you do with micro. They use some kind of food lab magic to do that.

That's why it's best to eat homemade popcorn in big handfuls, so you're bound to get some buttery pieces in the mix!
