This one appears to be the same as the Char-Griller, it appears to be a popular thermo with a lot of positive feedback (which is another reason I went with the chargriller). It can be had a little cheaper than MRP on amazon. http://www.maverickhousewares.com/et732.htm
I'm also looking at the auber temp controller to round out making it the ultimate "kooker" for the investment.
Its super efficient
Holds a steady temp so it doesn't need constant tending
It is a versatile cooker
The thermo will wake me if something critical happens during the night. This means I can get a worry free nights sleep which is very valuable when you have two toddlers...
I can cary on about my day without worring about temps of meat or smoker thanks to the remote thermo and controller.
The controller will reduce the odds of the something critical mentioned above happening
All for less than $600 bucks
Most important of all, everything that has came off of it has been great (even the over cooked steaks). I over cooked some chicken thighs (~185 to 190* wanted them to come off at 165*)the other night due to timing issues (wife was off schedule getting some other things out to the grill) and they were still moist and tender.
