LexMark makes good combos. They use regular ink jet cartridges which are cheaper than those toner replacements. I do believe that the Lexmark X73 is Mac compliant.
MacFormat said that it has "some rather elegant drivers for OS X", whatever that means! Make sure you get the latest drivers from HP's website if you buy the machine.
If I were in the market for this type of kit, I reckon this is the one I'd buy (at the moment).
