I am considering buying the whats a microcontroller activity kit. I would like to get the version 2.2 because it is cheaper. Will it hurt to get the 2.2 instead of 3.0? Please leave feedback.

    Well, you can look it up on the Parallax website. From the 3.0 PDF:

    ABOUT VERSION 3.0
    This is the first revision of this title since 2004. The major changes include:
    - Replacement of the cadmium sulfide photoresistor with an RoHS-compliant light
    sensor of a type that will be more common in product design going forward. This
    required rewrites of Chapters 7 and 10, and adjustments in other chapters.
    - Improved activities and illustrations of servo control in Chapter 4.
    - Moving the “Setup and Testing” portion of Chapter 1 and the Hardware and
    - Troubleshooting appendices to the Help file. This was done to support both
    serial and USB hardware connections, and other programming connections as
    our products and technologies continue to expand. This also allows for the
    dynamic maintenance of the Hardware and Troubleshooting material.
    - Removal of references to the Parallax CD, which has been removed from our
    kits, reducing waste and ensuring that customers download the most recent
    BASIC Stamp Editor software and USB drivers available for their operating
    systems.
    In addition, small errata items noted in the previous version (2.2) have been corrected.
    The material still aims for the same goals, and all of the same programming concepts and
    commands are covered, along with a few new ones. Finally, page numbers have been
    changed so the PDF page and the physical page numbers are the same, for ease of use.

    You are aware that the V2.2 comes with a few different components than V3.0.

    Europe in its infinite wisdom, banned the CdS photocell when they banned all heavy metals from electronics imported to the EU. Legally, Parallax cannot ship the V2.2 to Europe.

    And practically, everyone has gone over to the new technology that the V3.0 has because it is not economical to have two productions lines certified for different parts of the world.
