You will be very happy with it i am sure of that.
I have both units and love them both to bits. Obviously the 115 is more desirable due to the 20x burning speed and the consistent burns with more or less all media. But the 112 is no mug drive. Its well worthy of a purchase , but if you dont have either then 115 has slightly more to offer and as others mentioned firmwares will be forth coming for this unit too.
