Hi All, Many of you have commented on my series on Instructables detailing my efforts to use a laser printer to directly print toner on copperclad boards. Once printed the toner is "fixed" to the PCB with acetone vapor and then etched as usual. My latest effort: <http://www.instructables.com/id/Modification-of-the-Pantum-2502W-for-Direct-Laser-/> uses a laser printer that is available new, with toner, for $25 USD!! Add a handful of inexpensive parts and you can print DS PCBs for under $40 USD. Mark
