Harbor freight has the nibblers on sale for 29.99. The reason I am leaning toward them is that they cut up to 16 ga. and the shears cut only 18 ga.
The only place I have found 5 ft wide it comes in .050 which if I figure right comes out to 16.5 ish ga. I have seen alot of people using the shears. If anyone is using the nibblers let me know how you like them or any problems. I am going to buy them 3/21 I am ready to see the skin on my trailer.

Thanks
John
