Our team has used this vector in ''E. coli'' strain JM109 extensively. Clones are Amp resistant and are recovered in reasonable yields from mini preps. One drawback is that the vector has read-through transcription that comes into the cloned BioBrick part from both directions. This problem is a major one when an "off state" is critical for the control of a device. Parts without a promoter are expressed in this vector, regardless of orientation (see [https://parts.igem.org/wiki/index.php/Part:BBa_J31009:Design pSB1A4 Part Design] for details). Forward read-through might be from the Amp resistance gene. Reverse read-through might be from a cryptic promoter, since no known genes in the backbone are in the minus (complimentary) orientation.
