I received this section a few days ago and just unboxed it last night to see what it was like.
First thoughts vs the Canadian offering.
1. The thickness / gauge of steel is much better to work with.
2. This comes in epoxy primer (unlike the bare Canadian panel) this is good to prevent flash rust.
3. The compound curves are there and so you won't need an English wheel to shape it unlike the Canadian suppliers piece.
4. The exhaust cut out and bumper reliefs and spare wheel support (impression) are much much better on this piece.
Overall for a replacement section I give it 9.5/10 - It may need some minor shrinking on the top edge to get the curvature spot on but otherwise a very good section.
I spent weeks trying to make 1, weeks trying to make a reproduction section fit and so for all those reasons I'd say it's worth paying $500+ for..
Hope this helps others.
