If it is going to bother you, like it would probably bother me, I will look for and pay up for a brand new unit. They are still out there but you got to search. Good Luck and stick with the larger screen whatever you do.
Pioneer is also selling their KRP-WM01 ultra thin wall mount for the 141 for almost half price. The trick is that you will not see the reduced price until after you place the item in the cart and go to checkout. Still expensive, but a very nice mount. I ordered one a couple of weeks ago.
