You see em for sale here in the buy/sell threads. I bought my 1015 on ebay, for about $80 shipped, brand new in the box. The 1313 i have i bought used for about $55 shipped on here. 2 rock solid servos for the price of one hitech, thats my idea of a good deal. When searching ebay use "ds1313" "ds1015" "ace 1015" "ace 1313".
