Blastgate Company has very good pricing on spiral, and a great assortment of fittings. I'm nearing a DC system rebuild, and was about to settle on 30 ga. galvanized--going to have to reconsider. And, at 3 1/2 hours each way, i'll at least be able to consider renting a trailer for pick-up depending on shipping costs. Hadn't heard of them before. Thanks Jim!!
