@persiflag: The only problem I’ve had with my Rock Elite is with the plastic dust cover hinges. They are far too thin and unsubstantial to support the weight of the cover when the lid is in the fully-up position, so one of the two "arms" (into which the cover slides) tends to snap off. They should have been made of something like aluminum.
By the way, I fit my Rock with a Zeta arm, a great match for the table.
