Some Duponts are soft flame and some are torch.
You will get a ton of opinions on which lighter you should buy.
Cheapest lighter is a ronson and some people swear by them and only use those because they feel it's pointless to spend more if you don't have to.
Then you get in to the Colibri price point, which offers many torch lighters in the $30-$50 range and have a year or two warranty.
Next would be the Xikar category, a lot of offerings from $30 to $100 with a lifetime warranty. The Escalade or Vitara would be my recommendation in Xikar lighters.
You then get to the higher priced lighters such as Lamborghini and even higher priced with Duponts. These lighters most people buy because they like the look and style of the lighter. They don't necessarily work that much better than any less expensive lighter, but that is where preference comes in to play.
Bottom line, pick a price point you are comfortable with, then figure out whether you want single, double or triple torch, what size tank(large or small capacity), do you want a punch on it, etc... and go from there.
