Sure they may be made in the same factory but I doubt that the owners of Ohana would do a personal set up for you like Mike and Tootka do.
Most factory-made imports are setup a little higher at the plant to enable the shops to lower the action, if need be, to the taste of the purchaser. That is planned by Ohana. I have discussed this with both Louis Wu and (via e-mail) and Ken Middleton (via telephone). With shopkeepers like Mim, you do get personalized attention and if you state your preference for high action or low, you get what you want. Mike at Mainland will do the same. The key to satisfaction is communication. Like the old saying, "Ask and you shall receive."
