Thanks for the info on SpaceX
I hadn't heard about his plans to man-rate the Falcon V. That's good news. What Musk and his company are trying to do is remarkable and I wish them nothing but success. If his Falcon V succeeds, it'll likely kill the Delta booster. According to Aviation Week, the Falcon V has roughly the same payload as a Delta IV (not the Heavy) for a lot less money.
Still, his approach will probably cost several million dollars per seat to LEO. The market for that kind of ride is, I suspect, extremely small. If space tourism is to be a real market, I suspect the price will have to be in the $100,000-300,000 range. I'm not holding my breath.
