Never used their stuff, but Jagger Bush has a cheap 120v controller.

I really like my Brau Supply controller. It's a little more spendy, but very high quality. I have an older 15 amp controller. Here's a link to their new 20 amp.

Thank you for the recommendations TexasWine. I was actually reading a thread I believe you started awhile back regarding the Brau Supply system. I was sad to see that they use the Ranco Controller now instead of the 15 amp controller that you got. I wouldn't be able to use the 20A controller they have now in my 15A outlets, correct? Even with a 15A to 20A adaptor isn't that dangerous?
I'm happy to pay a little more for a quality 15A controller.
