Yes, Adzam mate, don't we all! The killer is the price we have to pay for them, but, as you say, nothing else even comes close for that wonderful relaxing, realistic sound. Superb. If I could afford them, I'd use nothing else!
Just the very thought of having to go electric leaves me cold. Bloody airbourne food blenders!
Mind you, in view of the fact that the electric motor is never going to quit in flight you could always use a personal stereo with earphones playing a recording of the engine noise of the actual full size aircraft! Hehehee.
