My advice is similar to harpmaker's but for slightly different reasons. The TOA PA amps can be found very cheaply second hand and are designed to be used for fixed PA insallations in shops and factories where the 12 Volt facility exists in case the mains power fails. The trade will tell you that they don't break down.

On the negative side they are heavier, need a tiny bit of tech savvy to put together with a loudspeaker, and of course are not a single integrated unit.

For positives, the sound quality is excellent, typically have two, three or four inputs, but importantly are very cost effective secon hand. Yes there are other high quality names, but the only other brand that I've used is Audio Telex (Australia).
