The parts listed here should all be stocked by Digi-Key [http://www.digikey.com/] and the part numbers and prices reflect that of Digi-Key on 12 Feb 2004.
Note: The MAX743 is not a Digi-Key stock part and will need to be ordered separately. I am currently stocking them if you can't obtain one directly from Maxim.
