I understand your point Wojtek, but to continue your analogy with some real world experience, I don't give a damn if they kiss my ass when I take my BMW to the shop, I would rather not be taking it in. By comparison I never took any of my Toyotas to the shop. To bring that to the modeling world, if I can get the same performance and reliability (or better) out of a less expensive engine, you are darn right I am going to buy it. If JetCat hikes their prices more, then Artes turbines and SimJets look that much better -- especially if the Artes turbine really does hold up as well as the JetCat and since Artes is the electronics guru who apparently feeds technology to the other companies and . . .
