I second (or third, or many more) the calls for AC/DC ones, particularly Luci-esque (which I have).
Would also be great to be able to replace the hideous centre apron card and 'hold for info' ones, especially with something along the lines of the red and black lightning bolts on the translite, and the red and yellow AC/DC logo.
I still can't get over how Stern shipped such horrifically ugly (and low DPI / print quality) stuff on either the standard machines or ones like the Luci. They literally look like they've been scanned using a circa 1998 combi printer, then printed onto kitchen paper. It's that washed out and grainy.
Would happily donate for the latter and pay for whatever the speaker panels cost.
