Plastic Welding Kit

I want to repair some of the plastic things around my house, and superglue doesn't always fit the bill. I want something that acts just like a soldering kit, but for plastics. I want a stick of plastic (glue guns are somewhat close) that I can hit with a specific amount of heat that will melt it and fuse it to the plastic I'm working on. It should be color-matched as well, with a Pantone color mixing kit, or I should be able order specific colors on the web. The plastic should be recycled as much as possible, and recyclable #1 as well. I just hate throwing plastic away, and typically it cracks not because of a faulty design, but because I'm a total klutz. Bonus track: Let's you sculpt with the stuff for fun.
