what accessories am I missing?

You sound pretty well set

Altho you have a DigiQ  there will be times  you operate without it.

I guess it's best to cook by temp  (thermopen)  but I added a dedicated timer to wear around my neck  to keep from opening the egg too often

I went with Thermoworks TimeStick   I really like it

The iphone clock has a timer  but it wasn't that easy to set, reset quickly.

Just a thought when you have $20 burning a hole in your pocket

My AR came setup with the R&B package.  I'm looking to add the extender soon

No plate setter or heat deflecter?

Bottle opener?

You got the Turboencabulaor? 

And here's a link detailing the tubroencabulator.. >-

mangrates

+ 1 on the Smokeware cap they are awesome. I don't think any egg should go without one. I just got a small egg and cant imagine using it without a Smokewear cap.

Ice chest full of beer.

Here is the spec sheet for a GE Turboencabulator... Straight from the publication library.  This thing freaking rocks! 

Freezer full of meat?

@tarheelmatt - I believe everyone should have at least one Turboencabulator in their BGE arsenal.  I've never seen the GE document you posted.  Rockwell has done the bulk of the work on the Turboencabulator, as shown in this video link: https://www.youtube.com/watch?v=rLDgQg6bq7o

@nolaegghead - the model pictured was also designed to engender multiple functionalities, as has been the trend with recent incarnations of the Turboencabulator.  To wit: the tennis ball launcher for canine exercise in the lower left quadrant of the machine.

These eggcessories are on the cheap side like less than $10, but really handy when you need to stir up the air to get the fire going. On the left is a hand crank blower and on the right a battery operated "personal" fan.
