it's my first time posting here so please bear with my ignorance 
i'm not much of a video connoisseur, but due to anal retentiveness when it comes to my audio set up I’ve decided to get rid of my tv, which is a decent $700 32†Toshiba…. This is my reference point when it comes to home movie watching and I’ve never watched any movies on any projectors outside of movie theatres… so obviously I need help
I think that I can get a shap xg-e800u for $500 or a sharp xg-h400u for around $700 USED.
1. are these good deals? if yes which one would you recommend?
2. is it ever wise to buy a used projector? Both swear that the lamps are barely used… but obviously there is no way of knowing.
3. I know that the screen size greatly affects movie viewing experience, but such low end projectors measure up to my tv in image clarity?
4. if you recommend not going with a used projector then could you please direct me to lowest priced units and dealers where I could purchase a projector that fits my needs? (as I noted above, I’m not much of a connoisseur, I just want something cheap and reliable that can match my mid priced tv set in clarity)
THANK YOU!!!
