Advanced Minds

I am interested in buying a video/data projector, and wondered where in Dunedin I can view either of tha above models of video projector, or anything similar in the $2000-$3000 price range. The thing that interests me the most is how smart these projectors are with video input - I hear some cheaper projectors scale input from DVD projectors up to the native resolution of the projector, producing a jagged picture in these cases, and am wanting to be sure I don't get something with that problem. Cheers
