Let someone else spend the money on new technology and wait until it's a reasonable price, assuming it even works as advertised!
As for the aerospace aerogel, I read a blog from a guy who bought some online just because he was a tech junkie. The first thing he did was take it out of its container. The second thing he did was find out just how amazingly fragile it was when half of it was crushed by taking hold of it between his fingers. That was a lot of money for not much fun (or long lasting fun...)
I can't buy something without first considering whether I could just make it myself instead. How'd I get so screwed up?
