ferrite i believe it's called.

Make sure nobody is interested in buying flatscreens, I come across them from time to time and a quick craigslist search reveales wanted ads for people wanting them for parts/or to fix.

Last one was a 19". I had to go a block out of my way on my way home from school. 2 mins for a quick c/l search. 30 second phone call. Guy came that night with a $20 bill.
