I'm a fan of constant lighting, it's Tota and Omni Lights for me. Tota lights are also the same as halogen flood work lights, which I also have as backup lighting for larger events, use to use them all the time for lighting stages at beauty pageants (now I use Tota Lights).

PVC frames work great too! Had to buy some PVC just the other week to make a huge scrim to cover a huge window on a shoot (I always carry some painter's canvas with me to stretch over it.)
