I have a panel that will fit a 150 L or 75 150M ...I made it for a local 150 owner who has not picked it up...it's Dove grey on top and darker grey on the bottom.
I am raising my club prices $25 for the Uppers and the same for the lowers ($50 total for a total cost of $750).
If anyone is interested they can have this panel set for $700....
Oh, and it is set up for circuit breakers, which would be the easiest part of the installation;-)
