Need help on screen masking

I have built my HT room and am basically happy with it. The only real improvement I can think of is replacing the fixed 120" 4/3 Dalite screen with an electric masking screen. I looked at the prices and they are not compelling. My questions are as follows:


1) How hard is it to make a professional looking masking system?


2) Does the resulting screen look as good as say the dalite system


3) can I utilize my existing Dalite screen


4) Where are the best plans for making an electric screen and what are the costs involved.


5) I would love to make the whole system controllable with my MX500 remote- is this possible.



These questions may have been answered before but I am still confused. I have the ability of a small child when it comes to designing and building( my father in law is in charge of construction) but I want to provide him with all the parts and designs.


Thanks guys!
