Does the 912iS have any drawbacks by not using "real" dual ignition?

    I think it will be a matter of maket forces and corporate bottom lines.
    The 80hp 912UL is only for european market where there is a power restriction in some countries.
    If the regs change the UL will disappear.  Same for the last remaining, nearly orphaned 582 2-stroke.
     
    The price difference  between the 912 ULS and the 912is is smaller than it appears.
    The 912is INCLUDES the Engine Mount frame that the ULS does not.
    That closes the gap by another $1500, placing them within $1,600 of each other out the door.
    Admittedly, the 912is requires a more expensive Glass Cockpit, but that is not necessarily a bad thing considering all that they bring with them.
     
    Ultimately the aircraft manufacturers will likely drive the market. 
    They will not want to market both engines so the Newer and Better and all that, will win out.
     
    I can see the 914 bowing out in favor of the 915, do we really need two sizes of Turbos?
    Once you have made the turbo decision, cost is not a major consideration; Go Big or Go Home, rules the day!
     
    The future will tell.

    The UL is also nice because it can use lower octane fuel.

    Geoffrey, You have a perfectly good reason for preferring the iS, but here in the US I'll never have to make a four-hour trip without a chance to refuel.  Anyway, I was giving reasons why the older ULS might still be preferred, despite some of the advantages the iS clearly has.  I'll just add that, since I am doing my own maintenance, and having been introduced to the computer-complexities of the 912 iS at an official Rotax service course, I am very happy that I do have the 912 ULS (also quite happy that I don't have a 914, but that's a different kettle of fish).
