We use Snappy brand white popcorn (comes in a 4lb plastic jar) and pop it using canola oil in a "stirrer-in-the-handle" popcorn pan from lehmans.com, We use butter with Flavacol movie popcorn seasoning (only takes a little and it's available on Amazon, Ebay, etc, etc) to get that "movie theater" taste.
You can also find a wide selection of popcorn at lehmans.com.
Popping in a pan/pot is something of an art and using the proper heat level is important. Don't get in a hurry and turn the heat up to max - there's a proper skillet temperature for popping popcorn.

The best popping temperature is between 400 and 460 degrees Fahrenheit. These people should know what works best for their product.

Two French engineers did lab tests that indicate the proper temperature is 180C (356F). Read the full article for details.

Unless you're using the same pot and heat source as one of the references is, your results will vary but you at least have a ballpark figure of somewhere between 350F and 460F for the popping vessel temperature ;-)
Get an infrared thermometer (maybe $20 at Harbor Freight or Walmart) and do your own testing. See how long it takes to get your amount of cooking oil up to that temperature and what heat setting can maintain that temperature with the kernels in the oil. Then make small adjustments to find which temperature works best for you.
Good popcorn works well in a hot air popper IF you load it correctly - almost never more than the recommended amount and sometimes a bit less. That will also vary a bit with your AC line voltage as differences in the voltage applied to the heater make a difference in how hot the air stream is so you may need to experiment with the amount of kernels. Properly done, hot air popped corn can be light and crisp.
We've used both hot air and stove top poppers. Hot air popping is fine for convenience and minimum cleanup but I've decided that I prefer the flavor and texture that oil popping gives. YMMV.
