I got the reflector material from Specialty-Lighting, but it only comes in packs of 4 2'x4' sheets. That's enough to make 8 mini's and it costs $150 for the 4 sheets. Comes out to $18.75 per reflector if you can get a few guys to go in with you on them.
It is stiffer than the SunTunnel, but it was easier to work with.
Where can you buy that style reflector for $19?
