For ever and ever I have been using MSR WhisperLite stoves. It is a lightweight, trusty and durable stove. They do clog from time to time but because they are so basic, they are fairly easy to unclog just by taking a couple of things apart. I have found this stove to be perfect for hiking trips where weight and size are issues. I used to lead hiking and canoeing trips at a summer camp and we still used stoves that were purchased many many years ago. One negative, which is I think to be expected, is that one must be very careful in cooking as it is somewhat precarious because of such a small support and surface area for cookwear to rest.
