Personally, I think most machine made scrolls look like crap. Especially when made out of dinky little flat bar bent the easy way, with flat ends where they fit into the scroll die.
That said, I also own a scrolling machine that cost more than a new toyota- well, a Yaris, anyway. But it has the power to scroll 8' long pieces of 1/2" round stainless into curlicues, and I build or modify my own dies as well. I am currently working on a fence that incorporates around 600 scrolls, all hot forged first, from 1/2" stainless, so the machine will pay for itself on the one job.
You wanna see the ultimate scrolling machines, look at the germans-
The reason for this expense is to try to approach the look and materials of a handmade scroll- most every good looking historical or contemporary ornamental iron using scrolls had every scroll made by hand. This makes for shapes and materials not possible with your little jig- things like half penny ends on every one. And the slight variation between each makes for a much more pleasing look.
So ultimately, I think if it were me, I would sell the scroll jig. To some screen door maker, or something.
