I have always been a fan of Coleman lanters. I used to have about a dozen of them, but when the ex and I split they had to stay, and have probably been added to the big fire I am sure she had, burning anything around that was "me." Coleman fuel is widely available, and if unopened has a long shelf life (and opened also, from my experience). Always have a handful of spare mantels available, and a spare generator (for your model lantern). Those are about the only two things that ever need replacing on a Coleman. Put a little oil on the pump leather (or rubber on the newer models I believe), and you are always good to go. New Colemans can be expensive, but if you drive around on weekend mornings, looking for that familiar Coleman green (or red for a really old one), you can usually find one for $10 or so. A dual fuel model would seem to offer a better selection of available fuels, but I have never had one of those. You can buy a reflector that attaches, and blocks about half of the globe, thereby directing most of the light in one direction, which can be handy sometimes.

My wife collects kerosene lamps, they always have fuel in them, and we always keep some spare fuel around for them also, just in case. They are a tad more dangerous (tip over can equal fire), but all of our kids are grown and gone, and we haven't reached the age where we might fall over with the walker and crash into a lantern.

We also have a couple of battery (D and AA size) lanterns, mainly for the fast start-up they offer. They will give us the light needed to fire up the big boys...
