Would appreciate some advice before I commit to changing my projector. Currently have a Sim2 Domino 20 which is about 1 year old. I use RGB input from an Xcard in the HTPC or VGA from the graphics card. Was thinking of upgrading to a 30H, but I can probably get a second hand 300HD for cheaper. It doesn't have any digital input which I am not using at the moment anyway. How does the picture quality of the 300 compare to the 30H ?? Would it be a bad idea to upgrade to a projector without digital input at this stage ??
