Epson EX7220 - asking price $220
Epson PowerLite 705 HD - a few listings priced as low as $100
I am thinking of going with a screen size of 120-144". Would any of these do the trick? Preferably the cheaper ones? The picture doesn't have to be perfect. If I mount it on the roof the closest I can get the screen is about 15'.
Ok we'll throw out the first two.
The next three that you've found will work with a 144" screen at a 15' throw distance.
The quick answer or my choice would be to go with the HC2045 placing the EX7220 and the HC705HD second place but coming in at a close tie. I'll explain.
The EX7220 and the HC705HD are very close to being the same projector with regards to specifications. They are both 720P machines with regards to resolution. The EX7220 would have an slight edge over the HC705HD with regards to contrast (Black levels on screen) and the price on the HC705HD is terrific if you're guying on price. Brightness of the two units is essentially the same. That's assuming they are both in good condition.
The HC2045 is simply the better unit with regards to picture quality. The HC2045's contrast ratio is much better than the other two by a factor of 10+ which will make the on screen image much more pleasing if you compare the three side by side. The HC2045 is also a full HD or 1080P unit with regards to resolution and as such may give you better picture detail and sharpness. The price is not too bad and if it's Craigslist, most people will come down on price 10-20% if you're good at horse trading.
Again, my opinions are with the assumption that all three are in good repair.
You may need to buy a new lamp for any one of them as they are used units and it's maybe a good idea include that factor into your thought process.
So my preference with regards to performance:
- HC 2045 contrast ratio 35000:1 - 1080P resolution
- EX 7220 - contrast ratio 10000:1 720P resolution
- HC 705HD contrast ratio 3000:1 - 720P resolution
Again the HC 705HD is a killer price.
With regards to mounting the projector on the roof... All three units have what's called an off set where the center of the projectors lens will need to be placed just below the top of the screen, a few inches, upside down in your case with roof mounting. If you go with the VisualApex 144" screen, this should not be too much of a problem as the 144" screen is 104.5 " tall and your roof is 108". VisualApex does make some extension legs for the screen or you could elevate the screen with some bricks, etc.
I think you'll be very happy with the HC2045 paired with the VisualApex 144" screen. We have a very expensive purpose built theater inside our home but we always look forward to using our simple backyard theater in the summer. There is something about being outside, watching a movie under the stars that adds a whole new layer of fun to the experience. Good Luck
