User Review: MSR WhisperLite Internationale
Price Paid: $40
An excellent stove overall and a joy to use. I bought it used from a good source in great shape. I've had no problems with it at all and have managed to get the heat control thing pretty well mastered - or as best I think is achievable.
I travel a lot and so use a lot of different fuels. A tip I learned from the early Primus stoves: if you have to use fuels that produce a lot of soot on startup, carry a little methyl hydrate (methylated spirits) with you for priming. No more black muck on everything when you pack it all up.
One improvement I could suggest would be to somehow make the fuel line more flexible as it's tough to get it to go anywhere, including back in the bag.
