are any of these better and easier to use for the novice? and hopefully inexpensive. my car is a 2002 honda crv with 135,000 mi. thanks.
No. Just don’t be fooled into thinking they are a magic box that ‘tells’ you what parts to replace. They only indicate ‘where’ to start looking.
If you just want a basic unit to read codes a $30. ebay unit is just as good as a high priced unit.
