No background plasmid

I've been looking for a plasmid that has a multiple cloning site in the
middle of a suicide gene, so that an insert is nessesary for the
transformants to survive.  So far the only one that I've seen is one made
by Invitrogen, which I am told you can't plasmid prep yourself, but have to
by it from Invitrogen every time you want to use it.  

Has anyone heard of any other plasmids like this?
