Fran, I've been playing arrangers since they were invented. Never had one fail.
The joystick spring on Roland G800 broke about a week after I got it. I took it out and cut off the broken part and it worked fine.
The G800 seemed to be built like a tank, and weighed about as much as one but it had bad paint and the keys were clumsy feeling.
HankB's PSR 2000, had several drinks poured into it. Mostly Vodka. It had burn marks all over it. It was dropped and was never cleaned. As far as I know it is STILL in service for the third owner. When we sold it, we guaranteed it would last at least 24 hours!
Now, feature-wise, I suppose they have to leave some stuff off the MOTL keyboards in order to sell the TOTL models.
To me "Home" means it's too big and too heavy to carry around!
