which PA system

[MIKE 450]

I'm going back on road, solo acoustic singersongwriter with my trusty avalon silver series and my 28year old washburn which Sam Irvine left into the Avalon workshop to be repaired,I wore it out but Sam the man said one of his boys will bring it back to life,be careful Avalon this little guitar is my baby.But my question is to all you giger's out there has anyone ever giged with the yamaha 300 PA I was in a well know music shop in Bangor and the guy there swore by this little thing, I tryed to check out some reviews but had no luck. I was lucky in my old band we had a road crew the PA was massive that was 12 years ago, so can this little thing do the job in small clubs and pubs he say's he sold a load of them I want to beleve him it looks cool and Ive just turned 50 HELP.
