It depends on what you're planning on doing with it. For me a variety of tips is what would be important. One for heat shrink tubing is what I use the most. One to fan the heat out. And one to concentrate the heat would be the three that I use the most. I bought one at a garage sale 10 years ago for 10 bucks it's done me very well. I have coworkers that have the harbor freight and the DeWalt and they all do well.
