I purchased this to replace my 30 year old International model after the fuel line started leaking (not a product flaw, more of a lack of use over several years). I knew the International was capable of multi fuel use, but I never used anything other than white gas anyway. Comparing prices between this whisperlite model and the current international model, I made the decision to go with the standard whisperlite model.Straight out of the box it boiled 3 cups of water in 4 minutes. This is a proven stove with no competitor on the market in its class. Price at $44.97 (prime exclusive), weight at less than 1 lb, efficiency is incredible, durability is out of this world.If you are looking for a reliable, lightweight backpacking stove, this is an awesome decision, even at a potentially higher price of $89-$99 range. Plus, with minor maintenance, it will provide you with solid performance 30 years down the trail. Thank you MSR for making such a wonderful product. A lot changes over 30 years. I'm so happy that this product has stayed true to service and reliability.UPDATE: I've seen a lot of reviews that criticize the "simmer" capabilities of the whisperlite stoves, both the standard and international models. I will say the control knob on the older model pumps allowed for more intuitive flame control, it just felt better rolling the knob as opposed to twisting the valve. Nuance, I know, but in the conversation... I have been able to fry an egg over easy with no problems. It does require a deft hand and watchful eye, but is certainly possible with little fidgeting other than managing the flame at its lowest burn point. I would not discourage anyone from purchasing this stove due to the simmer capabilities. It will simmer and cook on low flame as long as you watch it and monitor the amount of food in the pan/ pot. Stay vigilant.
