looking for a device

I am looking for a device (existing,to be designed or to be assembled from existing parts)

Requirements:

1. Inexpensive < 200 US$
2. Has a Bar Code reader
3. Has Ethernet controller
4. Is Programmable. * programming tools ( compiler, loader, etc. ) are readily available or not required.
5. Has LCD ( small is fine )
6. Has Keypad, not required but nice to have

Variations: A. Magnetic or Proximity card reader instead of Bar Code Reader B. Build In Modem instead of Ethernet controller

Any Directions or Suggestions would be greatly appreciated

Sales people are welcomed, as long as you have above device to sell.
