Hello, I was thinking of buying a projector.  I was wanting one to use outside this summer on the side of the house with a king size bedsheet.  I have a yard sale find Infocus IN35 projector, last made about 2007/2008.  Money is always a consideration, but I was thinking about significant picture improvement possibilities.  I've tried the Infocus once only, on inside wall briefly, it has only VGA, S-video, and RCA video inputs.  I was considering instead getting an Epson 5210 or 7210 projector with cheap blu-ray player for source.  I have no access to decent internet, so I'll be using the round shiny discs.  I currently have no blu-rays however, only dvd player with dvds.  Would it be worthwhile to try the Oppo 103 in connection with the epson 5210 or 7210, so I could make use of my current dvds?  However, for I've seen blu-rays around, it may not be a big deal to access rentals or buy.  Or, would I be better off getting a cheap blu-ray player and a better projector, such an Epson 8350?  I'm not interested in 3D capabilities.     Or, 3rd option, should I keep the Infocus IN35, use Dvds, and get a decent sub to augment my sound?  
       I currently have a pair of PSB Image 5T Floor model speakers.  I used them in conjunction with a $20.00 Realistic thrift shop amp for outside movies 2 summers ago.  I was impressed with the experience and so were my family and neighbor.  Inside, I power them with a Sony GX50ES receiver/amp, probably 23 years old, but going strong.  At this point, I'm not wanting to put money into 5.1 or 7.1 amp, I'd likely only add a center channel speaker if I did.  I have a Velodyne Servo100 that gave up the ghost, surround foam loose all around it, it is also 23 years old.  Would I notice much difference between what this sub did and lets say... an Outlaw LFM EX-1 or SVS PC12 Plus?  Maybe I should have posted in Subwoofer forum.   I've just been thinking of posting for a while, and I thank any and all for their input.
       I tried to post my TV room picture, dimensions, unable at this point.
   My TV room dimensions are:  10.5 feet wide, 19 foot long, with a 7 foot opening to our kitchen dining area, sliding glass doors on opposite wall, and a bay window behind the TV.
