Remember that in a retail POS setting, you want to minimize the
number of devices and cables.  For choice #1, to really be
marketable you may have to build your own box containing the computer 
board, a custom USB keyboard, and a kiosk printer like one of these:

Otherwise, you will have your client computer device, a custom 
keyboard, and the receipt printer all connected with cables.

You might get away a Linux thin client device where the power
button can be programmed to run a script when tapped intended
for you to specify the clean shutdown script.  (Holding
it down for 4 seconds will force an immediate power off).

Here is another possibility:  Look for a programmable
credit card authorization device.  Those have small screens, 
buttons, networking, and a little thermal printer all built in.
You just need it to send a network request to the m0n0wall
box through the network and print its response.
Check with Hypercom at http://www.hypercom.com if they
have a device that would work for you.
