I have a set of binary vectors with the general structure:
LB ocs3'PacI selectable marker AscI nos5' or 35S5' lacz RB
then using a shuttle vector I have cloned in the bar gene, the nptII gene
and the hpt gene.  So I have vectors that are essentially identical but
have different selectable marker genes (I have all three 35S versions but
only nptII and hpt driven by the nos5').  
I have also made versions of these vectors that have a 35S 5' intron GUS
ocs3' cloned into the unique NotI site in the lacz, these have been used
to develop transformation systems.  A number of shuttle vectors that clone
into the unique NotI site in the lacz have also been made including:
NotI-MCS-NotI; NotI-35S5'-MCS-ocs3'-NotI; and NotI-MCS-GUS-ocs3'-NotI
(with all three reading frames so that tracriptional and translational
promoter GUS fusions can be made).  Because the lacz has a functional
blue/white screen cloning into the binary is relatively easy and cloning
into the "small" shuttle vectors is also relatively easy.
All of these vectors and shuttles are freely available.
