I have a Brunton Helios for several years. I paid around $35 for mine (on sale) at a local outdoors shop. It is really well made and I hight recommend it. But at the same time, I have to agree with many others on here that a simple Bic is still a simple way to go.

The Helios is built well........quite waterproof. Refill is easy too.
