We leave "SOLD" items on our website for machines that we often repair and provide parts for. This is to give you an idea of the products we typically carry, and direct you to alternatives you may not know about - we often have substitutes for out-of-stock parts, and are happy to recommend workarounds and different solutions to common problems.
