I am the king of the triple post!!! Well, maybe the prince, second to bob-bobby. Woohooo! PRINCE!!! Purple Rain!!!

Anyways.

I assume that you're looking for a combo amp, since you want a simple piece of kit. I noticed on the Google that I did for the Samick PM-4V that it runs for about $500 USD. Is that your price range? I checked out some other PA systems in that range, and there are some really nice looking sets, but they aren't combos.

Here's an example:



Another interesting one by Fender. It's called an LTB PA Package. Runs for $399 on musiciansfriend.com. I couldn't find too much info on it, but it seems to be a 4 channel, 120W, comes with cables and a mic.

For all the above, click on the pic and it'll take you to the link.

The forum will only let me post 3 pics per post, and I don't feel like quadruple posting, so here's a link to the trusty ol' Fender Passport PA system. This is the PD-150, a 4-channel, 150W system with either 1 or 2 mics (zZounds' description is a little confusing and contradictory, I think). $639.95 USD.

Oh, and for all the above (esp. the zZounds links), be sure to shop around first, because I ran into some varying prices even on my quick search, but I just posted the first link I found, not necessarily the cheapest.
