[ale] Can Bad Video Settings Fry LCD Monitors?

The $ 15,000 I mentioned was for one of those electronic pianos that David brought up.  I know I'm not even in the league to LOOK at a Steinway for purchasing purposes.  In any case, I think I'd rather have a new decent house for $ 300 K.

I do like the idea of handcrafting something, be it a piano, car, computer, whatever, that someone ELSE is willing to pay multiple $ K for.  As an engineer, I find it hard to get into that mindset of super luxury items.  I heard about a $ 10,000 cell phone once.  I just cannot imagine paying that, for that.  So, it would probably be difficult for me to market it too.
