CEN linked disruption markers needed

We are trying to clone the gene which complements a mutant, but have
failed to clone it out of a CEN library. We know that the gene is CEN
linked, and we are entertaining the possibility that we can not clone the
gene because the gene would bring a CEN, and two CENs is toxic for a
First question: Do others have experience with this problem (and any
We could map the gene by crossing to strains with CEN linked markers, but
this will prove difficult to analyze because a reporter present in our
strain (and absent from the mapping strains) is needed to determine the
We have another idea: if we can get disruptors (for non essential genes)
for each of the chromosomes, we can easily make strains to do the mapping
in a strain containing our reporter. 
If you have a disruptor (URA3 preferred) for a non essential CEN linked
gene, please contact me.
We know our gene is not on chromosome III (LEU2) or IV (TRP1).
