There is a nice 3M one going for $65 on eBay right now. Do a search on "LCD
overhead" and you will get several hits on eBay. The only problem is they
usually do not work with Macs since they are set up for VGA or better from a
PC with direct monitor output. I remember when the units were selling to
schools for $1800 each and we who were teaching computer programming couldn't
wait to get one. Now we just use the projection units hung from the ceiling.
Today's cutting edge technology certainly is tomorrow's old hat. Wonder
what's next?
