I've just been reading linuxprinting's endorsement of HP machines, but
the bottom line (for me) is the relatively inordinate price of HP's
stuff.
The same applies Lexmark (also highly recommended) once you decide you
need a duplex printer.
And the same applies to Samsung with regard to consumables - a bit of
crazy price for toner cartridges compared with the Brothers, which is
a shame because there's an excellent offer on the ML-3561N (33ppm,
networked, 1200x1200, Postscript 3, duplex, 500 sheet tray) in the UK
if anyone is interested:

Anyway, thanks for all replies.
