A dream to play, maybe. A nightmare to afford...
Does anyone remember what happened to the home organ market, after it priced itself out of affordability? Yep, that's right... you are playing one now. Arrangers, affordable alternatives to the organ took over, pretty much completely.
Push arrangers in general into that stratosphere of price, and you'll see exactly the same thing. Let's face it, Oasys's are not exactly flying off the shelves, are they?
