I am trying to buy a popcorn machine for our family room for Christmas. I have seen several, different prices. Does anyone own one, about 5ft high. Maybe I should be on another forum, but I don't know where to look. But if you have one of the popcorn machines, please tell me about it. Does it last? I know there is a USA, more expensive, but probably better and one made in China that I can get at either Sams or Costco's for about $250. How much popcorn does it make at one time.....What does I need to look for? Thanks.
