So I'm extremely intrigued about making my own planar driver I've been doing research and I realize quite a few people make their traces by using a Solid ink printer and chemically etching away the aluminum the issue is i cannot find any used ones that are not either $800+ or broken what other options for making the trace do I have or where could i buy a used solid ink printer? I've heard about some trying to use a laser printer for its toner but getting mixed to bad results.
