The screen you have linked at NewEgg looks very similar to my Infocus screen (except 76 diagonal and the rod at the bottom of mine is black instead of white).
I think it would probably make a very good budget, starter screen (I'm very happy with my el cheap matte white Infocus screen; I'd like a larger diagonal, but the 76 inch diagonal actually fits perfectly on the wall I've got it on and 16:9 material is plenty big; it's just 2:35 film material that I think would benefit from a larger diagonal).
Anyways, just make sure you can place your projector about 14 feet (I'm guessing) from the screen or your projector won't fill that screen, even with maximal zoom. You'll have to sit closer than the recommended 2x screen width recomendation, so you may see some screen door effect, but the pq is so beautiful that you, like me, probably just won't care.
Good luck!
