71 Cuda Billboard Vendor

Who is the go-to for Cuda billboards? Jegs sells Phoenix Graphix, classic Industries sells a non identified vendor, both are made in USA and claim Authentic Mopar Restoration (which I'm sure doesn't necessarily mean much). Is there a common preference or maybe a common source to avoid?

Having first hand experience with both Phoenix and Performance (for 71 road runner strobe stripes), the Performance ones were much better quality and more accurate. Dave (original owner of Performance) is no longer with us, but I have no reason to believe the quality of the product is any different.
