Need to create barcodes in Illustrator for label

[JoeM]

Using Illustrator CS 5.5. I tried a vector barcode generator but the barcodes are not being read well on two scanners I've tested with a print out. Not sure if the tolerances are right as far as white space around the barcode. I'm reading up on that now.

Does anyone have a suggestion for software or a plugin for Illustrator? I know people used to use Barcode Toolkit but that looks to have gone away.

TIA
