Yea, the price to feed the thing is a bit ridiculous.  My dad actually bought mine for me.  He thought I needed a big game gun, incase I take a surprise trip to Africa or something.   He actually bought one for himself first, and liked it so much that he thought I should have one too.     
However, they're both just the basic Vanguard models.  He did recently however, buy a Mark V Accumark with the Boss brake system chambered in .338-378wby.  He's still waiting on it to ship from Louisiana, though.  I can't wait to play with them.     
I will say that for a basic Weatherby, I'm quite impressed with the quality/money of the Vanguard.  Not to mention, it's light as a feather.
