I'm after a M2 SSD. This is just for a single board computer (Udoo x86) so I'm looking for something small (i.e. cheap) if anyone has a second hand one lying around.

I can get a new 128 GB one for $60-70 ish, but that's total overkill for my needs so thought I'd check in here first. 32-64 GB is plenty for what I need.

The officially supported size seems to be 2260, but I don't really care whether it fits neatly in the case or not so long as it fits the socket. Official specifications are here for those that know more about this sort of thing than me.
