What is the "walk out the door" price?
Unless you have some ridiculous installation, I can't see why the price is that high.
(caveat, I'm used to wholesale, I haven't "paid retail" for anything in 10 years...but I used to work for a wholesaler)
Things I've been "given" over the years...(not just...
By the way, start here...

Unless you know the differences between the 3(technically D-ILA and LCoS are the same...) styles of projector...and why you might need lens shift or anamorphic...
A projector sales person can feed you whatever he wants to "make profit"...
A projector salesperson who didn't explain the differences/benefits of DLP, LCD, or D-ILA/LCoS???
A projector salesperson who didn't mention lens shift?
Find another store.
JVC period. Then it is if the "particular projector" has the features you need/want for your particular install...ie...
Anamorphic lens
Lens shift
Amongst others...
