Finding Solid State Relays

Where can I find cheap (under $3.00 US each) relays to hook up to my
basic stamp? I need solid state relays because the electromechanical
ones make too much noise. They will be going on and off pretty fast
so they have to have fast reaction times, also. Thanks very much.

    Reed relays are quieter than normal relays, and should switch faster. If
    that won't do, you may have to go with solid state.

    Have you considered triacs? I ended up using something like a solid state
    relay in an 8-pin dip package. I would look at the voltage you want to
    switch and look for a triac or other device which will do it.

    FYI, I ended up using digikey's PVT422ND dual relay package to use a stamp
    to switch a 320V Peak-Peak AC signal at about 6khz, which I used for an
    electroluminescent wire prjoect.
