I have handled some Muela knives in Spain and they are great considering the price down there. I bought a 6" bowie/hunter with a full, tapered tang, stabilized wood handle and brass guard. I am not sure about the steel type, but it is a vandium/moly type and the quality is good. Grinds are very accurate and the overall quality is impressive, considering that I paid around $35 for it two years ago in Barcelona!
Generally Muela have a good rep, but i can't vouch for that particular knife you want. It does seem rather expensive though. At that price I could think of a lot of other blades to buy, but like Gene says - if you really like a knife, go buy it.
