Depends on the technologies you want to work with, but assuming it's a single license and you use three of the five (seems to me to be the "core") ... around $9500 a year. Second license drops by 25%.

Edit: For what it's worth, I left a message and Mr. Rohm called me back personally the next day. Maybe I was projecting an image, but for all the world he sounded like he belonged in the halls of Princeton.   Technology is downloaded and you buy a license. Hardware requirements aren't huge (normal laptop would work). Must be Windows - but not Vista compliant.
