bead roller? where to purchase? what dies?

[t300]

Looking at getting a powered bead roller, specifically the powered Baileigh at the link below. Initial use will be creating filler plates for c10 firewall (ie heaterbox), new trans hump, console, etc. I don't think it comes with any dies but I would like to limit to purchasing 2 to start. Already have a manual roller but no time for a project to beef it up and motorize it.

Is there a popular die that everyone gets? I was thinking the 3/16 or 1/4 round bead and the 3/16 step roll . Thoughts?

Any favorite vendors to order from? Baileigh directly? Trick Tools? any board sponsors? Hope someone has a Black Friday deal! thanks!
