I just had my first experience yesterday.  I used the HP laser printer at work to make the photocopy art work.  I used a cheap $19 iron from a local hardware to transfer.  I used 1 part Muriatic acid to 2 parts Peroxide to etch.

I put the boards in a smaller portion (one cup to two cups)of this concoction and agitated them lightly with 2 of those disposable metal handled glue brushes.  It worked PERFECT!  Every so often I switched from board to board and rubbed lightly with the brushes (kind of held the board down with one and spun the other brush lightly).  Maybe 5 minutes later, I was down to clear boards.  I rinsed them, dried them and wiped them clean with acetone.  BINGO ..... 5 perfect boards.  I was so happy.

I basically used the info at http://www.fullnet.com/~tomg/gooteepc.htm and had great results.  Ken has lots of experience and there is alot of info there for the newbie. (like me)
