I have never used one, and I am not going to stick up for them, but I do know a little something about wholesale pricing and the way that soom manufactures work.
The Regulator is a spitting image of the Aeromotive unit, and I know that Aeromotive will sell wholesale and without any labeling at a significantly lower cost, remember the Aeromotive unit is fairly cheap to begin with. The lines are stainless braid (you can not use silicone with reusable AN fittings). The line and fittings are pretty cheap also when bought in bulk. So breaking down the cost, I doubt that they would have anymore then $100.00 into it and yet the Buy It Now price is $150.00. $50.00 profit for literaly no work.
I have looked into doing this myself with a number of manufactures, but the buy-in price/cost is to high for me right now.
Again, I am not saying that it is an Aeromotive unit, but you cant knock something without trying it just of who its from.
