Donny, Bingo! Yes, the beauty (to me) of the KP100S (with upgraded woofer) is that can perform double duty as both a main source & monitor for smaller venues and then as a convenient personal stage monitor for larger venues.

I'm curious now just 'how large' a room and maximum number of people (for arranger show concert venue) the larger more powerful KP200S can handle. Perhaps Jim Eshleman (the Pro) or other KP200S gigging solo arranger kb musician owners can provide those numbers again.

With my KP100S amp, I'm able to easily transport it on my ultra lightweight collapsible 'Superlite' hand truck: http://www.pstco.com/superlite_cobra.htm
I'm afraid the 'Superlite' hand truck is too small to fit the KP200S though. Curious what (sturdy, yet small as possible) portable handtruck would be the best match for the KP200S. Jim, I assume you're not attempting to lug & transport your KP200S around by it's top handle, right? What (if any) hand truck or cart are you using to transport your KP200S? Thanks, - Scott
