Screen's cost a lot of money, I would get the projector first. These new projectors are nothing like the projectors of old..they output a bright enough picture that you can enjoy them even on a wall in you home with the lights turned off. I used mine on a flat white wall for two months while I did research on the type and cost of screen I would need. Avguygeorge's idea is another good way to enjoy your projector untill you have made up your mind on what you need.
Screens come in all shapes and sizes, they also come with different amounts of GAIN. GAIN is the amount of help that the screen (they come in different colors and finish) will offer a projector with a lower light output or in a room that is not controled of all outside light. In other words, the screen you need for your projector and your room would (could) be different than what I need. You may even need..no gain.
Screen shape and size is another matter that should cause you to take a wait and see out-look. I would have bought a screen that was to large had I not had a couple of months to play around first. I am going to give you a couple of links to some screen info to read up on, I'll have to post another response though because I don't feel like re-typing this.
