So far as I know,

Linux has these, free.

Mac has free work in progress, probably not complete.

The Windows tools cost too much: at least, myself, I've never persuaded 
any Management to accept a truth that seems obvious to me: any design 
engineer working for hire and twisted enough to want to see the plain 
hex should see it.

Top of the line is:
Maybe more like US$1,000 per seat than $100 or $10,000.

Me, lately I've cared only about SCSI thru USB, not other SCSI 
transports, so I no longer remember if the available tools work 
elsewhere also.
