If I was still doing functions I'd most likely have a Fender Rumble 500 combo. I know it's not in the Vanderkley, PJB bracket for quality but it's a lightweight, powerful, single unit that's ready to plug in and play. You can sometimes get a bit pushed for time to set up at functions as well. The 500 combo could easily be put up on a stand as well so that you could hear it better.
