Best Option under $200

Im currently putting together a family project for a living HT. We just painted the walls last night dark grey and need to know if painting the wall for a screen is one of the best options. Currently looking into either building a screen but dont know where to get the material and how much? Paint that I would go with would be the RS-MaxxMudd or SF, whatever is best for alittel ambient light. My third option would be to buy a pull down screen and use my 52 LCD for regular viewing. Who makes a good pulldown screen? Im wondering how many people use there projectors for there day to day tv? I have alittle light coming through but not much. I would rather use the FP and put the 52 in my bedroom. Im also wondering how big of a screen to go with? Looking into a 100" or 106" diagonal screen with viewing distance at 13'. Is that to big or should I go bigger? The room is 16' wide and 13' long. The projector im considering would be a Epson 8500 UB, Epson 8100 or AE3000. First time building a HT so if I left anything out let me know. Thanks.

Forgot to mention the only reason im doing a screen under $200 is because we are buying a house in about a year or more. Once we buy a house ill have a dediacated HT room.

Thanks. Starting to more of a detailed search. Im leaning towars building my own screen. I have all the tools but now trying to find the best material. From what I have read alot of people use Dazian for the screen and black felt.
