I haven't heard of Digikey before. I'll have to give them a looksee.
For the recycler, have you had any issues or concerns with reused hard drives? I'm aware of how to securely wipe them and whatnot, but I feel like my nerves would still be on end to some degree, no matter how many times I reformatted or securely erased the data on it. Similarly, is it safe to assume that they have some kind of thorough physical cleanliness policy regarding hardware? I've listened to stories of computer repair techs who receive desktops that have literal cockroaches crawling out of them.
When I think of a recycling plant my immediate gut reaction is "dirty", but I feel like that reaction is unfair, if not unfounded. I've never been to that kind of place and am not really sure what to expect.
