You can get a flat panel for around 100 dollars and have it be a decent painting size. So thats 100,000 for 100. I'm sure you can negotiate the price so you aren't paying retail for them as well. While yes 100,000 dollars is "a lot" it isn't that much compared to the project being discussed. If you are building the castle, 250 flat panels at 100 dollars each won't seem alot to you.
