I also have a similar experiment to tag HA epitope to the C-terminus of 
my transmembrane protein.  I couldn't have found any commercial vectors 
with C-terminal HA.  

Anyway I PCR'd to get an insert with HA tag to subclone into a regular 
yeast vector.  Now I'm trying to to immunoblot to check if I made it.  
I'll keep you updated regarding this.
