Just recently purchased a samsung SCX-4100 and it is great.
nullSamsung SCX-4100
Picture
It is cheap to buy ($389.00 AU), has a proper paper cassette, not a gravity feed mechanism.
You can hook up through either USB or Parallel.
Scanning quality is very good.
The copier function works very well.
You don't get ADF, duplex printing or faxing capabilities, but for the price I'm hardly concerned.
You also don't get color printing, but you don't require it. Personally I'd purchase a seperate color printer like the Canon IP3000 to complement the samsung if color was required.
