I got mine at www.emistycreek.com - they used to sell on ebay, but I don't think they do anymore, since they have their own site set up now. Mine will hold 5 lbs, but I only use 4 in it, I think the 5 lbs makes the bars too big. But that is my own preference. Upland has molds, For Crafts Sake has molds, Kelsei has molds, but he has hurt his hand and am not sure if they are still making them right now. Lots of sites have molds, just depends on what you are looking for.
