Those little Behringer boards work very well - quiet preamps, nice EQ controls, headroom, channel inserts, built-in effects (effects are a little noisy for some reason)... The prices on those things are amazing; our band uses a 12-channel one.
Reliability isn't so good with behringer stuff though. That euro-series would include a great board for you guys, and I'd highly recommend them - wrap it in a big'ol blanket or something for transport, and turn stuff on one at a time, in proper order. We were blowing up compressor channels by the month until we stopped throwing everything on at once with a power strip!
n8g14: You can get tons of help here - we'll steer you right. ..But c'mon, man - you have the internet; at LEAST do the tiniest bit of study on the subject, Man. At least learn the very basics of mic level / line level / speaker level. Power amps are big and heavy, and have big, hot heatsinks hanging out of them, or whirring cooling fans; they have to pump hundreds of watts of power to drive the voice coils in the speakers that rattle your windows. Mics generate a tiny, tiny electrical signal directly from infintessimal little waves of pressure in the air around them. Obviously you need to amplify this tiny tickle of voltage into a big, honkin' current to drive the speakers. --So here's how it goes:
1) Mic to preamp - the preamp turns mic level into line level. Line level is small, but at least has enough oomph to be routed around and distributed between various circuits and components and processors and whatever, without having to be all balanced and shielded to keep from being suseptable to picking up noise and static every time someone straightens their sweater. Splitting and mixing, EQing and level controls and all that is done at line level. Boards that have mic inputs have mic preamps, so everything going on in the board (after the preamp, that is) is line level. Mic level is measured in milli-(thousanths-of)-Volts; line level is measured in Volts.
2) Power amps take this nice, easy-to-deal-with line level, and goes the other way - it turns it back into a not-so-easy to deal with signal again, but this time it's because there's so MUCH power involved. A big pro power amp has enough power to kill you at the output terminals - tens or hundreds of Volts, at tens to hundreds of Amperes!
No, you can't drive a speaker from the line level that comes out of a euro-board.
Now go Google-up some more learnin' for yourself! (anyone have a link handy to a decent PA tutorial?)
Be careful: it's easy to misappropriate even a thousand dollars on PA stuff if you don't know what you're doing, and end-up with bad sound.

(edit) Oops - I forgot somthing important: That's why you hear reference here to "powered mixers" - a powered mixer has a power amp built-in, so that you CAN plug speakers directly into it.
