Dear Larkin,

As you're in Europe and money is a concern you could perhaps consider looking at a Behringer 2x250W system with 10 channels and built-in multieffects for around about Euro 820 - 850 new.

You can of couse get better, and it would be worth looking secondhand, but the price escalates quickly with quality and extra power. For pub venues and Irish music I would suggest 2x250W (bridgeable to 500W mono) as a minimum in order to get above the din of the punters.

Peace
