    I am in the market for a transistor testor, but don't know what to look for.
    What makes a good transistor testor? Anyone have any recommendations? I
    have found one used Supercricket TF30 transistor/FET testor for about
    $30.00, and another apparently higher-end unit for $150.00, but have no idea
    why one is so cheap and the other is so expensive. (Sorry I can't remember
    the make or model of the higher-end unit.) Input is greatly appreciated. I
    am just a hobbyist, but I want to keep up the trend I have started of
    getting decent equipment rather than cheapest/easiest to find.

    I have always used an will not catch all types of failures,
    but does work pretty well. I have seen some transistors, especially ones
    used as switches, only fail at higher frequencies. For that failure, I just
    remove the load, connect the scope and watch the square wave as I drive the
    frequency up. There are alot of other ways to test them in circuit too, just
    one example here!
    There are a bunch of pretty sharp consumer electronics guys over at that may have some good suggestions for you.

    Dave Guest! GOOD IDEA! :) Thanks. I'll do that.
