I have a blue rhino that crapped out on me after 1 week, sent it back under the warranty and the service was great, I had a new blue rhino in about 2-3 weeks. That one crapped out after the first tank too, I gave up on sending it back after that. The best lighter I have owned was a Colibri...it lasted about 4-5 years before the fill valve got stuck, but from what I understand I was lucky and a Colibri lasting that long is a rare occurance.
I just got some Ronsons and have been impressed, here good things about the Xikar as well. Those would be my two top choices.
