Based on my experience with OMRON VT-RNS, I would not consider this machine unless you are running high volumes of a limited number of assemblies. Programming and debug took a lot more time than than other machines in the same price range. After debugging the programs the machine ran well enough, just a lot of time spent "cleaning up" the inspection program after the auto programming. Look at Mirtec, Yestech, and MVP too.
