*** UPDATE 2 TO THE ORIGINAL QUESTION ***
Thanks for all the great advice.
I think a good plan is to get a PA speaker to start, at least 100w, and then add a 2nd one ASAP.
I am trying to navigate through it all of the option and I am not sure about 2 points.
(1) Should I get a PA powered-speakers or non-powered-speakers?
(2) Should I get a PA with a built-in mixer or not?
(Note that I am trying to remain budget conscious here.)
(Note that I am trying to buy something that can be integrated into a larger system-- such as buy one speaker now and then daisy-chain more onto that later as budget permits.)
What do you think?
Please advise.
Thanks.
