I have an ancient HP 4M-Plus with duplexer that hasn't jammed in years. Great for saving paper when printing long manuals. For colour I have an HP CP1518ni colour laserjet because the toner never dries out and clogs the print head...
I just don't do that much colour printing, I guess - and it only cost $250 a couple of years ago.
I'll stay with HP, but probably never get another inkjet printer.
