If those printers as shown on their website are the ones they're offering, i'd be very cautious about signing up for their printers.
We bought 6 of these (konica minolta magicolor 2430dl) back in mid 2005 for our admin staff when we decided to switch to printing letters with colour letterheads and we had no end of various problems with them, with us even resorting to contacting konica minolta - while quite helpful - kept sending out engineers to repair parts of the printers which then kept breaking again.
A year later we just decided to bin all 6 of them and buy replacement HP Color Laserjet 2600n printers. Since putting them in - apart from replacing toners - we haven't heard so much of a peep from admin staff regarding printer breakdowns.
EDIT: Forgot to mention, toners are at least £80 for each colour, £50 for the black.
