Led supply http://www.ledsupply.com/ was just able to get me a 3023 de 1000 led driver. It is the same as the 3021, but with 6 inch wired leads instead of pins. Should make it easier to work with and less likely to short in the metal housings most of us are using. At the time of this writing they had 2 left as this is a brand new item. It isn't listed on the website, you have to contact sales in order to get it.
