I thought shade fabric looked cheap in my Hummert catalog. Those prices are mostly for unfinished material, without the edges taped and grommets installed. Tape and grommets are actually more than the shade cloth itself.
I just purchased two of the 12x18 Aluminet 45% panels from this link:

$117, shipping and tax included.
I'm glad I ordered the finished panels. The confirmation email I just got said they ship immediately, but the unfinished material takes 3-4 weeks to ship.
