Generally I recommend you buy these directly from Lotharek. I don\'t get any discount and I can only offer it for a higher price, because I pay sales tax, shipping and fees plus the same price you get. The only reason I do offer some for sale, is because if you buy this item from me and also your Atari from me, I will, if you request, install it for free with your purchase.
