I did the same. Had a Masterbuilt (cheap) for years and figured out time and temp. Before that I had a Sausagemaker (really cheap) with no insulation and just a rheostat, no PID controller. Just a hot plat with a pan of wet sawdust on it really. I was able to get some good sausage out of it, but that's about it. Now I'm in BBQ heaven with my SM066.
