I bought the Siamese System second hand from someone, and what I found was that it was a pain in the backside to use reliably. Not to mention that it was one of the buggier pieces of software I ever purchased. I know I gave up on it soon after - not sure if I still have it or whether I sold it on at some point.
A big thumbs down from me, and while it did most of what it claimed to do, it didn't do it very well.
