Avoiding expensive mistakes requires experience, i.e. trying all the options to find the lowest cost, best quality, highest profitability. 30+ years later of endless hours of work, and we can tell you. Beware of the used car salesman who will sell you anything to harvest your money. We ONLY recommend best, but will show you how NOT to spend money. No other manufacturer or distributor will do that for you, and none of them have printed with the products they are trying to sell to you in production for 30+ years. Watch carefully, and take notes. Compare.
