Start taking a look at some of the reviews for 3D movies. Not big name reviews based on watching the movie in the theatre, but reviews by average Joe people who have viewed them at home, on a home 3D projector.
You will be able to find out how many 3D movies there are that you would like to view, and also how much joy other people get from watching 3D movies at home on their 3D equipment
I find a lot of people who have seen a 3D movie in a theatre and at home, seem to like it better viewed on their home equipment...Seems a large picture from a projector also wins out over 3d TV's, seems in the case of 3D, size does matter. DLP also wins on a almost ghost free 3D image but the new Epson 3020 has gotten good marks this year for it's 3D.
