I want to get some input on weather or not I should stick with Infocus projectors. I purchased my first one (X1) about 4 years ago and was happy with it until it started the color wheel buzz noise. I called Infocus about the problem and they offered to upgrade me to a refurbished SP4805 for $99 plus my X1. After doing some research on the 4805 I jumped on the offer and I've loved this projector for the past 2 1/2 years. Now it has recently developed the light tunnel issue and I am not a happy camper. I am now considering the the SP 7210 after reading many great things about it but I'm hesitant because of the problems I've experienced with my previous Infocus units. Should I get this projector or consider other brands? I'm looking to stay around the $1-$1200K price range.
