It's not really that hard. My pid-thermostat had screwconnectors for all cables. All you need is cable stripper pliers (or a knife/scissors) and a small screwdriver. But my thermostat is not chinese, so I don't know how to hook those up, some of them need an external relay, mine has an internal relay. I can take some pics in the morning if you like. The things you need aren't found in a home-improvement store though, I'm afraid. Well, maybe you can find a cooler that you can use.

Basically you screw or solder the SSR (solid state relay) on to two terminals, your mains cables on to two terminals, and the sensor on to two terminals. And then you hook up your heating element to the SSR and mains (depending on how the SSR looks). Easy peasy.
