Zar - what kind of PA system did you get for $170?! Please don't tell me it was a Harbinger!
I checked out one of those Epiphone A/E's 2 years ago when I was shopping around for an a/e, but I wanted something that sounded full when played acoustically, and it's small body didn't do it for me. For my under-$300 budget, I had narrowed it down to the Epi AJ220 and the Fender CD140sce, and I scooped up a Fender barely used for $199. I added the extended warranty for $20 and when the electronics gave me problems one time I called up the extended warranty place and they sent me a full refund+ with a Guitar Center gift card for $227.
I brought the guitar to the GC tech, he fiddled with it, replaced the battery and its worked fine ever since!
