sorry folks for the delay in posting.Naturally I will fill you all in.
But some questions answered from above to me choosing this one.
I have tested other PJs aswell and mightily impressesd with them
I have seen the higher spec hd81 in action and wow...happy to go with optoma,even on a lower spec machine.
Choosing this 1 cold is a risk naturally,however price is a major factor for me,room is wired for 1080p and 1.3hdmi, and seen as this is my very first projector I dont think its right i go in straight away for a 4k machine,feel I need to show the whole projector thing some respect and cut my teeth with a lower but seemingly suitable machine.
(I cant stand when people just passed their tests and daddy buys em a £20k straight away when not experienced or worthy yet-if you understand this then you will see where I am coming from).
I am more than happy to learn my trade at the hands of optoma and then see where I am in 2 years.
