Starkeeper,
When the storms arrive, I'll be shutting down my keyboard, and both computers, as well as unplugging them ALL from the wall

Can't take any chances there.
It's been a while since we last spoke, how's the PSR-550 going for you, or have you changed models? I have two keyboard purchases coming up very soon. One will be the new Casio WK-3700, and the other will be a good upper end arranger. Have a few in mind, Tyros, Korg PA series, and so on.
