Because we do A LOT of business through Mitsubishi via Numatic Engineering (Drives, Encoders, VFD's, Cables, etc.) and through Rockwell via Allied Electric (PLC's, I/O, terminal blocks, push buttons, etc.) We would just rather keep these two vendors if at all possible. We use a product in our machines and we use it for A LONG time so we feel the need to keep our vendors close. That way if theres a problem its fixed right away. Honestly, I've never even heard of Red Lion. I just googled it. - ok I saw it... looks like their list price for an 8" is $1999. thats nearly double the price im getting the Mitsu one for.
