Well it's a matter of economics. I called the local Yale dealer today and his price was $116 but he didn't have it in stock.
I then called Ed's surplus pumps and after exchanging critical measurements I determined he had the correct pump for $17.54 plus shipping so I ordered it. I questioned the guy on why the pump was so cheap and he said it's a Mazda automotive application so why would one give a dealer so much more for the same part?
This lift is going to be used at a automotive repair shop for occasionally lifting engines and misc. work and probably once a month or so. Definitely not everyday use.
Thanks for all the insight.
