I've had a bunch.  Different manufacturers make different quality Laguiole knives, the quality ranges from superb to ass.  I have purchased most of mine in France so I'm not versed on what is online.  That is an 11 cm knife, I have 9cm and 11 cm (11 with and without the corkscrew).  I can open wine bottles with my 9cm in a pinch though.  I think that price is reasonable for a good quality knife.

Chambriard is another French knife that I like.
