I am looking at buying a home cinema projector for the first time. I have seem some great deals on the internet that include free screen, cables etc. However, is it worth going to a hifi dealer, paying their (higher) price for the projector, screen etc and have them install it all, or is it easy to install/ setup yourself? I won't ceiling mount my projector so will need a portable stand, and will mount the screen from my ceiling. However, I'm thinking as I'm breaking my projector virginity, maybe it's best to leave it to a specialist? Is it worth the extra cost?
