Technology changes all the time so I’m marking this as advice in October 2019. There are 2 options – buy new or buy refurbished. If you buy refurbished, do note that Chromebooks have a total shelf life of around 6 years so check its AUE (Automatic Updates Expiration) as it will be a pain updating after this date. I’m pasting an image of the newest models available according to a Google Back to School Education day here. Click on it to make it bigger.
In terms of refurbished models, CAMARA and GreenIT are the two market leaders in Ireland and both of them are great!
