I have an older one and I got one from EH.net/IronKey. I love it. It is so rugged. Normally I am afraid of breaking them in my bag and I wouldn't trust them to be carried with my keys, but this thing is solid.
I like all the cool features and the cross platform support too.
I've seen the hourly rate from $150-$250 and I would guess that this would take 20-40 hrs depending on the services and the size of the website. That would put the range between $3,000-$10,000.
I have taken and passed both tests, and I would say that the overlap is a maximum of 40%. Not having the course material will make it much tougher to pass the test. I have Counter Hack Reloaded, but I haven't read it yet so I an't tell you how helpful it would be. Good luck.
