I just spent a little while checking out the INA website (
www.ina.com). They are a German company with distribution partners in many European countrys, South Africa, and Australia. Nothing I could find in North America (or the western hemisphere for that matter

). And nothing I could find gave prices. So, while the unit price may or may not be attractive, the shipping charge from where ever to N.A. is going to be ruinous.
robotic regards,
Tom
