Hey Tommy, I have lived/worked in a Snappy only independent shop for the past 10 years & have found after purchasing & getting used to the different format type of the Maxisys Pro that I purchased 3 years ago that Snappy is becoming 2nd rate as far as aftermarket scan tool functionality. On going updates is awesome in comparison to 1 or 2 a year & the J-Box is the magic that allows flashing a breeze with the proper manufacturer subscriptions. Just my 2 cents.
