Constitutive vector for yeast

[NEWLIN_C]

I'm looking for a Constitutive vector for a 
potential yeast expression system.  I've 
tried the usual (Stratagene, Invitrogen, 
and Clontech catalogues).  Stratagene had 
what looked like a great one (pEFT1), but 
for some reason they don't sell it anymore 
or never got to the point of selling.  I 
only seem to be able to find inducible 
types.  I'm still at the exploring 
ideas stage of this project.  Anyone got 
any good ideas where I might find an 
accomodating vector ?
