I ordered the $89 rev 1.5 special and I guess they ran out because there is a handwritten scribble on the invoice "free upgrade". Sure enough I got a rev 2 stick. Another company may have merely sent a note that my order was on backorder or they sold out. It takes some class and customer service to upgrade to a better grade. I have never done business with them before, but you can bet I will again. They have gained a customer.
