Ever had experience with a vacuum coffee maker?

I am a huge coffee fanatic and am looking to buy a vacuum coffee maker/brewer. I need a little help on picking the right one. There are so many different kinds, brands, and styles. For now I am looking in between the Bodum or Yama stovetop (because they are reasonably priced). Then there are those that are not stovetop, but instead use an alcohol flame (which looks like a cool science experiment). I’m new to the vacuum coffee maker, and wanted some help or opinions on which to buy. Have you ever had one or used one? which kind? pros and cons? anything helps. thanks
