Powerplay P1 : Great for the price

Awesome piece of gear for the price. Seem to be pretty well made. Some people complain about the battery covers breaking - but if you take care opening them, you'll have no problem. I have 6 of them and all have their covers intact, despite fairly solid use and abuse.

Sound wise they are totally ok. You can't really expect audiophile quality out of a 50 euro amp, they sound ok and are absolutely adequate for use on stage. I haven't had anyone complain about the sound yet.

As far as cons go - a bit power hungry, but you can solve that by getting some rechargeable battery units (they also seem to have more capacity than your regular 9V batteries).

The inputs can be overloaded fairly easy, so you need to watch your levels.
