Back into the same thread topic about these things working well as a fresnel for much brighter image on screen for an 8x10.
I was at Dick's 5 and Dime in Branson, Mo. today and found one by Bazic Products out of Vernon, Ca.
The one that I bought at a traditional office supply a few weeks ago was around $12.00. This one was $1.99 and I can't tell any difference in quality or results.
Full size is 8.5x11, just like the more costly version.
