You should never consider any projector without mechanical lens shift. Even if the projector is ultimately ceiling mounted and you don't require lens shift any more, lens shift gives great advantages. For those who are not considering a permanent ceiling mount, then don't even think about a projector without this function.
I am considering the 6100.Out of my budget (96k),no lens shift and i don't need the 3D. So i came accross TW3600. It has lens shift and is available for 83k.Reviews are pretty good.
I am just bit skeptical if it is ok to buy a model launched 2 yrs ago. I really need the lens shift,it will take away my placement woes.
So can i go ahead with the 3600 or I should manage without lens shift and get 6100.
Note: I was earlier considering the Epson Tw550 and have reached the budget of 83k with great difficulty.
