Does anybody out there have any experience with these systems and who could offer real experiences (rather than sales pitches, or claims) if either type of AOI system is better, or the advantages/disadvantages of each. I realize cost is one, but what about performance? Thanks for this and past help, this forum is invaluable. -Ryan Jennens TelGen Corporation
