Nobody interested in the 250 ballast ? Just buy a casing with an FC2 connector with a lamp of course and you are ready to see your sps color up ... those with a 150 W fixture lagi better ... just buy a FC2 connector and replace your connector with the FC2 connector and you can interchange them anytime you want to use them.
