I also recently bought one of these scopes, and just to add to Andy's comments, the depth of view on 10x is very good, which (hopefully) makes this a passable HFT scope as well as for FT
I'm going to the range this afternoon to do the various 'set up' and ranging processes, so I should be able to add more once that's done.
And to answer Rob's question, I paid about £180 (inc P&P) for mine from http://www.ftxtarget.com/products.php
