But in your room, I'd say 19' would work out fine and the extra expense of putting it against a back wall wouldn't be worth it.
At that throw, you have a wider variety of lens options. The one's I considered:
- IscoIII - most expensive best, least artifacts - I got this one.
- IscoII - may be able to find used in the 700-800 range if ou are patient. *Might* work at that throw
- Prismsonic HE type lens. They had a DIY powerbuy that saved a little - dunno if it's still going. Has motorized option.
- Luizwens' chinese lens. Inexpensive, but not much really know about it yet IMO.
- Panamorph's but I believe they excel and VC lens, not HE. And I'm of the strong opinion HE is clearly the best thing to do for a CH setup. I have a new Panamorph P752 I will be selling if you don't agree. Like the IscoII, you can find them used occasionally if you are patient. $600-$700 range usually.
Depends on your budget and pickyness I suppose.
For screens and this PJ, I'm planning on the same size, curved Stewart Firehawk ("plain curve" not Cinecurve). I love the ambient rejection properties of the FH, the assistance with black levels it provides to DLP's, and with a curve, I expect it's off-axis viweing cone to be improved as well as doing away with the geometry distortion of using a lens (pincushion).
