Do you travel in private jets? Decorate your foyer with real Renoirs? Use the word "foyer"? Then there's no way you're going to get your gadget fix from anything you can get at Best Buy. You crave the most exclusive, the top of the line, the most unusual, and the most attention-grabbing technology, and price is no object. But there are expensive gadgets, and then there are expensive gadgets. We aren't talking PlayStation 3 expensive — we're talking gear so expensive you'll have your butlers pick them up in your gold-plated helicopter.
