I made a paddle out of copper tubing and fittings. It probably pulls more temp from my mash than I need but i tend to overshoot my temps by a few degrees anyway. My old mash paddle was a huge stainless spoon/spatula thing but the edges and corners were kind of sharp, it was beating up my braid. Wood would probably be ideal. Here is a pic of my braid and paddle:
