This was the first I bought and haven't really desired for much more since. It's very reliable and dual jet is perfect for dynavap, IMO. Perfect middle ground for all butane devices, really.

Oops, that's not .ca ... and crap, I'm sorry but doesn't look available there. It is avery good lighter, though so I won't delete...
I also really like the zippo inserts, just for fun. But they run out of butane quickly.
