hers a trick Pete. Buy the plastic pincab protectors from Greg-RTBB, and then cut some felt type protectors a bit smaller than the hard plastic pincab protectors, and have the felt between the machine and the pincab plastic ones. (they come in all different colours for u to chose from)

That way, u get the best look of the coloured pincab style protector, but u have the soft protection of the felt against the machines artwork. Best of both worlds. !
