I do, double sided. I have a laser printer (an old 600 dpi Epson); a
home made contact printer; a Dremel (helps with the vias); and a lot
of experience and fine tuning.
I think you can forget it without a laser printer, though. I've just
bought (ordered) an HP LJ 1300, but haven't tested it yet. Things should
even improve with it, I hope (i.e. I will get more good PCBs per wafer).
Well worth for prototyping (but not for production, neither small-scale.
For that there are companies like Olimex).
