DO NOT throw good Amiga gear away please! Even CRTs. Post an ad on CL or here to offer them cheap or FREE if you must.
Yes they are worth it, some of us like to use the Amiga with it's original monitor. Now if they do not work, that is another matter.
If you do ship them make sure and you pad the monitor on all sides, even the BOTTOM and TOP of the box. Thay way if it gets dropped it will minimize the damage to the case. I found old monitor boxes with the styrofoam works great for CRTs.
