I recently needed a new cover for my GS-1200 projector and found www.digitaldeckcovers.com. I contacted them and told them what I needed. They responded back to me very quickly with answers to my needs for a cover.
Courtney who replied was wonderful to work with in getting the exact measurements for the cover along with putting an opening for the handle of the projector. Once ordered I had it delivered to my door in about a week.
Their quality is great, fits perfect and the projector cover was priced right. I have included a picture of the new cover. I hope this information is helpful if you should need any new covers.
Cheers
Ken
