Replacement for Xerox 4112

[LG1]

I am looking to replace a Xerox 4112 when it comes to the end of it's lease. I have had specifications forwarded for a Xerox D110,Sharp MX-M1204, Canon imagePress 1110 and Konica Minolta bizhub Press 1052.

I would appreciate some feedback if anyone has knowledge of these machines, particularly the Sharp model as I have heard very little about Sharp digital printers.
