I am going to start buying alot of sheet metal soon and I am wandering who to go with. I keep hearing of all these other companies but hardly never hear about NPD. The sheet metal I need requires truck freight and after comparing prices NPD has the cheapest shipping to my residence. This would make a big difference seeing that no matter what site I go to the prices are only off by $20.00 dollars or so. Except for the N.O.S panels. I would like to hear what the experts have to say on this.
