Looking for used Apple iPads!

I'm looking for no longer loved IPads! As part of my volunteer flying simulator projects with air cadets, I volunteer helping air cadet squadron build simulators on Vancouver Island. I'm looking for Apple IPads that you don't use anymore that still work. We use them as instructor consoles. I only load one or two apps on them, so they don't need much in terms of memory or size. If you wish to donate one, message me.
