My experience has been that the zebra strips never make good contact again once they've been removed from the PCB; they deform over the years to take the imprint of the copper pads such that they are not smooth anymore. I periodically fantasize about finding a company that can manufacture new zebras for the M100 (similar to how new PC1/PC3 LCDs were recently manufactured by Robert B.) Am I in the minority? -Josh
