    I am looking for some advice on purchasing a PC USB oscilloscope. I have no idea what to look for and what to order. Can I have some guidance? I looked on e bay and they range from US$22.00 to thousands so really don’t know what to look for. If someone could suggest a reasonable entry level unit I would be most grateful.

    Secondly I have Brunelle CRT oscilloscope which I would like to learn to use. Can someone direct me to a site which has step by step instructions for a beginner.

    If you have a functional CRT oscilloscope at home I 'd suggest you didn't buy a PC USB one.
    The extra things the USB oscilloscopes provide (depending on model) is logic analyzer function and waveform capture. If you do need those things, then, yes, a USB o'scope purchase is justified.

    No label or number anywhere? Not even in the back?

    If you don't need anything above 40 kHz, then you can use the free program WinScope. It uses the mic in on the sound card to capture the information.

    I second this. I found a different free program simply called 'Scope' and it does the same thing. Beats paying hundreds of dollars for a bulky thing to sit on your desktop.

    There's a sticky thread in this section that includes a link video on the basics of oscilloscopes.
    http://forum.allaboutcircuits.com/showthread.php?t=64241

    There are dozens more oscilloscope (and other tutorials) on the same YouTube channel
