Here is a good Open Box deal on the Lexmark E260DN - $96.54
http://www.techforless.com/cgi-bin/tech4less/34S0306?id=CKxkHT4p&mv_pc=221I almost bought one, but discovered that it takes 220v. Looking at the technical reference shows that the printer requires roughly 500w while printing. A converter will add another $30 to the price to run it in the US.
I like the idea of direct laser printing, but lack the mechanical skills to do the modification. My experiments with DLP are centering around "pure copper polyester taffeta fabric" from here,
http://lessemf.com/fabric.htmlYou can print to it directly with a laser printer. Just print your circuit to a regular piece of paper. Then tape a piece of the fabric over the image and print again as with the toner transfer process. The difference here is that the toner is fused directly to the copper fabric. I have tried it and the image on the copper looks exactly the same as the image on the paper. The polyester seems to be a bit heat sensitive, however. The traces also accept Green TRF Foil. I haven't tried etching yet, but obviously the reverse side must be masked to prevent the resist covered traces from being etched through the back side.
There are other issues such as sheet resistance,
sheet resistance of 1/2 oz copper = 1 miliOhms/sq
copper fabric at 0.05 Ohm/sq = 50 milliOhms/sq
I came across this idea here,
