ideas on postscript all in one printers ?

Hi everybody,

I am planning to buy an all in one printer for my WinXP and my Amiga SAM (OS4.1 as well as Linux). Should be connected via network maybe plus USB. Therefore should be a color Laser Printer with Postscript.
Anybody an idea ?
Do you suggest a certain manufacturer ? (Because of Linux/compatible Betascan drivers ?)
At the moment I am looking at:

OKI - MC560
Kodak ESP 9
Kyocera FS-C1020MFP
Epson CX21NF
Lexmark X544N
Brother 9450CDN

Whereas the last two models are prefered, because they are cheaper. No Idea if there is a HP model...

Thanx for advise or ideas
