I have a question, I've read not only here but other places that it's best to use an unregulated power supply. Why is that? It seems logical to me to use a regulated power supply that keeps the volts exactly at what the PS is rated at.

No expert here but I think one reason would be most drives do the regulating themselves so no need to regulate from the PSU, and also likely that a simple transformer, Rectifier, Capacitor style PSU will be much more robust.
