THESE PRICES ARE FROM MY MOST RECENT CATALOUGES
FROM BOTH COMPANIES.  IF A PART WAS NOT AVAILABLE
THEN THE PRICE FROM THE COMPETITOR WAS USED.  RP1
IS NOT AVAILABLE FROM EITHER, RS COMPONENTS KEEPS
SIP RESITORS IN STOCK (PACKS OF 5).

THE PRICE OF THE PC BOARD AND ZIF SOCKET ARE NOT
INCLUDED.  THE ZIF SOCKET WILL COST $14-$30
DOLLARS.  THE PCB WILL COST $3-$15 DOLLARS TO MAKE
YOURSELF.

AT MORE SENSIBLE PRICES (MAIL ORDER/LARGE SUPPLIER)
THE TOTAL UNIT WILL COST LESS THAN $35 (W/O ZIF).
