I actually just came across this very video and was going to post about it and another one I found but thought I better do a search first. You did a really good job with this Steve, there are some really bad Lynx vids on You Tube like that toolstyevski one (or whatever he is actually called), that one is a total embarrasment.
Anyway this is the one I found, its a bit too long but very informative - dunno if this guy is a member here or not.
