yeah, PRS knows what hes talking about.

the least expensive PA system packages on the market are:

Kustom PA KPA4 $160
AudioChoice C100 $180
Squire $230

if i had to chose any of those, i'd go with the AudioChoice... its by SoundTech, a pretty good brand for PA. its also a bit more powerful then the Squire PA, which i would pick second.

these 3 arnt the best quality, but for a garage band just starting out, they should work fine. cuz all you really need is something to amplify vocals.
