I have read a few threads that lightly touch upon this question, but I thought it would be appropriate to dedicate a single thread to the topic. I am looking to purchase my first HT projector, and have it narrowed down to either the Sanyo PLV-Z2 or the Sanyo PLV-Z3. I am simply wondering if going with the Z3 is going to be worth the extra $300-$400. I will be running it through a DVI connection from my PC and using it mainly for DVD's and video games (Gamecube with component out). My room will be sealed off using blackout material to cover the big windows, so hopefully light won't be a huge issue. Will I see a marked improvement with the Z3 or should I hold down on several hundred dollars and pick up a Z2?
