Thanks 88V!
The final invoice was $2500, but I spent probably $3k total because I ordered two sets of acrylic templates over the duration of the project. First, was a two piece set based on the original L&R panels. Then, I pivoted to a one piece design, made some instrument placement adjustments, and asked for the second acrylic template to be sent for final fitment and markup.
As mentioned above, the original plan was to go with a two piece, but I ended up changing to a one piece for few reasons:
1) The original radio rack rails (which are also the center panel supports) were turned into swiss cheese from all the alterations over the years and I did not want to remake them. Superior could rivet new radio rails right to the panel, which is what I did.
2) The location of the original supports restricted available space on the left and thus, less flexibility to design a clean layout. I recall struggling to keep the EDM900 there while keeping the G5's centered on the yoke while working on the two piece layout. Plus, I had contemplated flush mounting the G5's and the EDM which would have required more space for those instruments, exacerbating the problem. Ultimately, I ended up choosing the panel mountings
3) Simply, the one piece reduced overall complexity.
Your impression of 4-5k is probably in line with a panel that includes their premium labeling/graphic options that could easily push the cost to 4-5k, but those weren't for me. I just elected for the simple gray with white labeling.
