1) Quack, regarding your choice, remember the sage wisdom of Colin Fletcher. "Choose your stove wisely. The only thing harder to get a man to change than his stove is his religion."
2) Regarding the field maintainability of MSR's, it is a very good thing they are field maintainable because they are clearly in constant need of maintenance. The MSR's
have improved with the introduction of the shaker jet but its a very poor copy of a feature that Optimus stoves have had for years. With Optimus stoves, you can clean your jets while the stove is running. The
only repair I've ever made on my Svea 123 which was purchased in 1985 and has been used constantly since then is to replace the filler cap to ensure the o-ring was ok. And if you want the ability to burn anything, note that the basic Optimus/Primus design has been known to run for months on end on..... penguin fat.
3) Regarding bike touring, I would stick to alcohol stoves for summer bike touring. They weigh next to nothing and the fuel can be purchased
in small quantaties at any hardware store in any town. Nobody wants to carry a gallon of Coleman fuel on a bike. You want to buy your fuel a bit at a time. As for burning auto fuel, see the following link.
