Any hints on recombinant protein expression in Pichia?

We are thinking about trying the system out for the mass production of
a 150 KDa cytosolic protein. Unfortunately, I don't know enough about it
to be able to judge manufacturer's claims about it. I would greatly
appreciate any hints, comments or suggestions related to the use of
this system. I searched DejaNews and there are only few hits there.
Among many questions I don't have clear answer to are:
Does anyone besides Invitrogen make the kits/expression vectors?
What vectors (pPICZ, pGAPZ, etc) may work better?
Is proteolysis indeed a very serious problem with yeast expression?
What kind of advantage vectors for secretable epression offer? Is
proteolysis a bigger probelm or a lesser one with them?
What could be the "real life" yelds in case of ~ 150 kDa proteins?
