I'm "POSITIVE" that I'll never own a DI !
The DI is a great engine format as long as it is new. The problem is that they are hard to diagnose and costly to repair. Your average jet ski technician is usually not qualified to be working on them and therefore starts throwing parts at them which gets very expensive.
A ski with a DI is like a Lincoln Continental.....you gotta buy it new, enjoy it for 3 or 4 years and then unload it before it eats a hole in your wallet!
