Oh lord I had a projector! It wasn't cheap too but over time I found it to be useless unless you have a room with your projector set up already. As for me, I don't have that many rooms to spare, so I used to bring the projector out when I want to use it and keep it back in the storeroom afterwards. What a hassle! So I'm sure you can guess that that projector is currently collecting dust, which reminds me I gotta go bring it out and wipe the dust off.
Projectors can be fun with kids around though. My brother's kids just LOOVE it everytime I bring the projector out and screen cartoons on it when they come over. I have no use for it now because my brother migrated to NZ 2 years back.
Projectors...don't buy them if you're not a school teacher. Even then, the school pays for projectors so that is irrelevant! LOL.
