Honestly -$100 to +$100 depending on whether or not you have to pay to have them hauled away, pay to dispose of them, are able to give them away or, get really lucky and sell them for a $100 or so on Craigslist. Honestly 7" ES sets are not worth a whole lot today. There is not a whole lot of money in CRTs anymore except decent condition 9" sets. I try to sell for a while on Craigslist and remember presentation is everything. It would be good to have one working you could demo and have screenshots in your ad, sell the experience as much as the projector and you just might get lucky. Otherwise donate to charity or give away from free on CL.
