Any prokaryotic transcription/translation system will work, if you 
replace the phage polymerase with the E. coli polymerase. You can choose 
extract with no T7 polymerase added, so the only polymerase present will 
 the bacterial one. This kind of extract is sold by Promega. Other 
extracts will require the addition of the given polymerase, so the 
replacement is also easy; or you do not need to add any polymerase at 
all, since it will be in the extract.

Not relation with Promega.
