My favorite lighter are both from IM Corona. My Old Boy has been great for the 13 years I have owned it, I love the control I get with the flame and the built in tamper is something I cannot live without.
In the picture, my Old Boy is to the far right.
The one next to my Old Boy to the left is my Davidoff pipe lighter. It does not have a built in tamper and I only use it when I get dressed up. It is a great lighter because the flame is similar to the Old Boy.
My other IM Corona is one I bought about 5 months ago and it is the IM Corona Pipemaster. What I like about it is the electronic ignition feature and the tamper is much longer than my Old Boy tamper. So far it has performed flawlessly and it also has a huge well for fluid.
I also have a Zippo pipe lighter but really dislike it. The flame is very unwieldy and I only use it outside in strong wind conditions. I think I have used it maybe twice this entire year.
