We're trying to budget for a home theater system, and I'm wondering if there's a certain threshold where you start to see significant diminishing returns. We can make it $5k, we can make it $20k, but if it's not going to be twice as impressive for twice the money, it's not worth twice the money, you know? What can I expect out of a $10k budget? Can I get nearly the same performance out of a smaller one? Should we go HD projection, or is the quality of 70-80" flat panels within reason for the same or better picture quality? This will be used for both movie watching, and hooking up just about every single gaming console available. We'd also like to do something cool with using an iPad as a universal remote for everything, if possible. Curious to hear your thoughts!
