Fujiflyer,
I use the HP LaserJet 1300 for black & white Laser Printing. (There is an HP LaserJet 1300n which has network capabilities, but it is much cheaper to just have the straight 1300 connected to router with a print server like a D-Link 704P.)
If you are looking for Color Laser, I have seen the Minolta Magicolor 2300W Color Laser Printer for as low as $300 in the U.S., but I have not idea what they price at in the U.K.
Take Care,
Richard
