When you look at the onlinemetalsdotcom website you'll find that a 24" x 24" piece of 1/8th thick aluminum sells for $42.00... and thinner gauge sells for even less. That's a fun website for the DYI side if the house.
$510.00 for an Aluminum cover for the ARC Ref. 10?
Wanted to replace the poly covers, but this is unbelievable!!!
