I think for long-term use, even if it's just a light user for a primary school should still get a new one. At least with warranty and new spec is more value for money. Imagine buying a refurbished notebook for a few months and it has an issue and there's no warranty..

Can consider this Acer Switch One, comes with a 1-year warranty.
