Behringer 180w head

[Little Dragon]

Been offered one of these for very little money, anything to watch out for?

What will you be using it for?

I have a behringer head somewhere that I bought because my main amp crapped itself 3 days before a gig and it was the cheapest amp on GAK at the time. It works, and makes sounds but that's about as far as it goes. I do remember it barely being powerful enough - it was pushed pretty high to stay in the mix, and consequently had little headroom. 

I think of it as a Toyota Auris of amps - acceptable white goods.
