Homebrew PCBs

The wealth of information in this group is overwhelming me!

I would like to avoid buying into the process with supplies and equipment that are not going to work.

Are there any particular copiers/printers/toners that are known not to work for toner transfer for PCB's?

I am thinking of buying an inexpensive laser printer to cut down on the ink expense anyway.

It would seem to me that if it is really all that easy to do I could use even a toner copier and simply copy an ink jet copy with the toner copier. I gather that one of the key elements is to have control of the paper that the copier is using.
