Do any of you know of any retailers that sell extruded aluminum rails that could be used for making the light frames? I've been looking at this on Amazon but I'm curious if there are any cheaper alternatives. I know I can go with angle aluminum, if I want to cut the cost even more, but I really like the look and rigidity of the extruded aluminum rails.
This is what I'm going to buy if I can't find anything cheaper.
