Shaun, the other thing to do would be to check out the website
http://www.cloudynights.com/ubbthreads/index.php?Cat=0
the guys there are usually pretty much on the ball when it comes to possible / probable scams for instruments as well.
Maybe you could get detailed information such as differences in production runs and performance etc.
Worth a try at least and the guys there are just as friendly and knowledgeable as people here.
