LF Inexpencive temp controller........

You can buy Rancos on ebay. Got mine for about $60 I think. Be careful you get the 120V model if you go that route. I accidentally got a version that requires 12VDC input so I had to buy a power source for it as well. When I wired mine I followed a tutorial I found online from some BBQ forum. Turns out those guys use them too.

By the time you hack apart a few good extension cords etc you're likely better off getting pre-wired. I love these and won't run a system without one now.
