    I'm searching for a CW Practice Oscillator that's cheap. Preferably one that's a soldering kit. Not sure what works and doesn't out there.

    Lots of (free) apps out there too, that’ll probably do what you want. They even generate random code at selected speeds to learn CW.
    Good luck, and May The Morse Be With You!

    I have an MFJ-557 that's like new I would let go for $30 including USPS shipping to lower 48.

    Find an old transistor radio. Form a feedback loop from the high end of the volume control to the high end of the speaker. Use series R and C. Experiment to get a good tone. Key the battery.

    Can't hurt to try. Might work.
