Just take into consideration, those 32 and 64GB emmc drive are normally soldered down and you can't upgrade to a bigger one. If you could find some with a standard hard disk drive, it would be a wiser choice.
The following refurbished HP Stream 14 for $160 is probably your best option. It is enough to do basic things like schoolwork and netflix. It sells for roughly around $210 new. It has very limited storage of only 32GB, Windows probably uses around 20GB of it leaving only 12GB for you to use.
The only way to expand storage is with a USB flash drive or SD card. Between the two I would use the USB flash drive since it fits in more securely. Some laptops do not allow a SD card to be fully inserted; so they stick halfway out.
I beseech you...do not get one with a 32GB eMMC drive. Just speaking from experience.
I have/had an Asus Transformer with one. It was too small for even the Anniversary update to run. "Not enough free space"
Nice little system, but get something with a larger drive.
