I'll echo the Xikar/Ronson opinions. A Ronson Jetlite is cheap (so it can be replaced when lost or broken) and available at most Walmarts and some drug stores. Xikar is a great option because of their warranty (lifetime, no questions asked). If you're a beginner, chances are it will not get purged correctly or get crap in the burner or something.

Had a Xikar Flash (single flame) that I used for years and worked great. Currently have a Xikar Pulsar (triple flame) that toasts a foot pretty quickly, although it's easy to over-toast.
