@KlausVanWinkle which DigIq did you buy? I've been thinking about getting something similar for my egg. Just noticed the DigIQ Green Kit on the BBQ Guru website for $197. Same kit with BGE logo is $419 on Amazon.

@ab1985 I got this one (went with the black one since I have a Primo grill). Ended up being the same price on amazon as on DigiQ's website. Used it agin this weekend to make pastrami, pork burnt ends and pulled pork. Went on a multi hour mountain bike ride and a long dog walk while it cooked.
I'm an egghead big time and wish I had the DigiQ. However Now that I primarily smoke several things at once I don't use the Egg except for grilling. Good friend of mine though bought the XL after I praised he EGG a couple years ago. He loves the DigiQ and says it works great.
@greenbeast That's partially why I got the Primo Oval Able to smoke about 4 things at the same time. This weekend I had the whole pork shoulder (9lbs) on the right grate, cured brisket flat (pastrami) on the left side. Drip pans below each. Then added the raised grates and two cast iron pans full of the pork burnt ends.
