Another Shackster welcome Don!
I think the site John was referring to is this one:
http://www.projectorcentral.com/proj...ulator-pro.cfm
Just enter in the make/model of the projector you're looking for, and you're good to go!
I'm using a DIY screen, and am quite happy with the results. Ultimately, I would love to go with an Acoustically Transparent 2:35 one, but it didn't fit my budget. Always something to upgrade to one day
Cheers,
