Oh yeah Flavacol is the best. I also really like using coconut oil.

Ours is 8 oz(1 cup kernels) but it's a true popcorn machine because it does the heating, and the turning. I really like it. It's enough to feed ~10 people with a little bowl, and it only takes ~10 minutes so it's easy to make seconds to share, and I've never had anyone have room for thirds.

We tried an air popper but I just can't get the right flavor
