The thermocouple reader is listed around $85 but goes on sale regularly for around $45 + reasonable S&H. The Tenma 72-7712 (shown) not only has 2 inputs but also has good (manual) temperature correction and collects data into your laptop (unlimited) or stores 100 points within it for downloading later.
Also shown are a source of type K thermocouples sheathed in stainless-steel, designed for kilns etc ...but just perfect for coffee roasters. I have 3 of them and others here have bought them too.
I had read about folks opening the door after first crack to slow things down before second. Not the most effective way to control temperature but it apparently gets the job done. At least, when it's too high.

I will point out that BehmorThing has a decent interface for manually logging temperature and while it's still called BehmorThing, all of the Behmor features can be turned off and then it works quite well for all other roasters. And it's free, but only Windows.
