It has more to do with attitude than total time. I have flown with some very fine pilots that were low total time. And some high time pilots that I couldn't turn my back on. As for businessman-pilots, one of the best ones I have ever dealt with had less than 1000 hours. When he flew, he acted like a professional pilot, no business, etc. If had to deal with business enroute, like clients on board, he had a professional pilot fly. He went to recurrent at least once every 12 months. In short he acted like a professional.
As for the accident you refered to, any aircraft will bit you in the ass if you let it, even a single engine Cessna. You want a hard T/P to fly, try a Merlin or MU2. They're harder than a 20 series Lear to fly.
