    --Trying to drive something with a Stamp; looking for a relay that
    can handle, say, 12v and maybe 2A. I know Parallax sells a board with
    relays on it, but holy guacamole, they want $300.- for it!! Can someone
    suggest a part number and where to look for just the realay?

    i would suggest using an optical isolator
    type relay.
    use something like a 2N2222 to drive it
    from your stamp to make sure you don't over
    do it.
    just an idea.
    you can use a conventional relay also with
    the use of the 2N2222, go to your local
    radio shaft and pick up a low voltage coil
    relay., they have them in 5 volt coils with
    moderate contactor ratings.
    use the 2N2222 to drive it.
    shunt the coil with a diode to absorb
    the flyback emf.
