stan2004 posted:That is, finding those insulating washers and related hardware pieces can be a nuisance. The insulated package is harder to find but can be expedient albeit at a price. You can't get a whopping deal on eBay as you can with the LM317T (metal tab) for less than a dime. While there are several eBay sellers of the insulated package, this may be the rare case where buying from DigiKey is cheaper!
That's true Stan, Digikey and Mouser have them for less than a dollar in quantity one, I didn't find one cheaper on eBay or places like Aliexpress.com
