Why not contact a local school and see if they could use them?
Or not

You will find most if not all schools are in a similar prediciment trying to get rid of old CRT monitors, I have 10's of 14, 15, 17, 19, 20" CRTs waiting to be taken away when I can get someone too cheaply.
CRTs are just junk these days, I havent brought a new pc for either schools ive worked at with a CRT apart from once.
