Wow, been a while since anything was posted here. Something I came across and thought was awesome for a lot of reasons is those 4'x8' insulation boards that are silver on one side and white on the other. Very light weight, casts or reflects really good light a long way, costs very little, and is almost disposable. I have a couple at each place I shoot at regularly but I can always find one for less than $15 at any Lowes, Home Depot, etc. It might seem like over kill till you try one.
