Here's a version that is apparently in-stock at DigiKey and less expensive 67 cents (vs. 87 cents). While I appreciate the convenience of 1-stop-shopping from DigiKey, given the ~2 week delivery time from OSH park, I wonder if going with an eBay Asia source is something one might consider. IIRC the LM317 goes for less than 20 cents on eBay (from Asia).
