I've posted some of this stuff before but figured I would consolidate a post with the accessories I use on my PB K24. I haven't spent hundreds and hundreds of dollars like some folks and know that others probably have better or different ways of accomplishing much of the same thing. I don't use any temp control gadget and don't really feel the need to. After gaining a couple years experience cooking on mine I can dial it in and maintain temps fairly easily. (BTW I did do the vent mods to eliminate any big leaks) Anyhow, these are the gizmos I use to help cook on the Pit Boss:
Firebox Divider Charcoal Fire Grate for Most Standard Size Kamado Grills, 10.5-inch ~$35 I haven't even had a chance to use this yet but it looks well made and should help with two-zone cooking. I'm not certain this is really needed as I've been able to cope without it for the first few years doing two-zone cooks but hey it's a fun new gizmo.
Pit Boss 76251 Heat Deflector, 24" ~$45 I know that these are now included standard with the grill. I had one break and PB/Danson's did replace without any problems. I use the OEM deflector a ton... it's used for all my Low and Slow Smokes (brisket, ribs, pork butt, etc), CI Dutch Oven cooks (roasts, stews, etc), pizza cooks, and all my baking.
Half Moon Heat Deflector Plate ~$20 These are 15" diameter and work well on the main lower grate to cook on the upper grate. I use these for two-zone cooking and also for a 2nd deflector in some cases, like for cooking pizza. These don't fit inside the legs of the OEM upper rack perfectly (more on that later). Also, I've split the OEM upper grate into two half moon grates to allow easier maneuvering inside the grill.
Indirect Cooking Rack, Extra Large ~$35 This is an accessory that I thought I would use a lot more when I purchased it. I still use it as a second rack for pizzas and such but it isn't something I wouldn't buy again. Unlike the OEM upper grate you can get the (2) half moons installed under it without any interference. IIRC this cooking rack is 15" diameter with the legs protruding out another few inches.
Outdoor Gourmet 14 in Preseasoned Round Griddle ~$13 This is absolutely one of the best accessories that I own ( I actually have 2) for my Kamado. I use it as a pizza stone up on the upper rack with both sets of deflectors in place and it works absolutely fantastic. I also, use this on the lower rack directly over the coals to cook my Philly cheese-steak sandwich meat.
Maverick ET-733 dual probe remote thermometer ~$35 I didn't provide a link because everyone has there own set-up for monitoring temps.
Of course there's all the other normal cooking stuff, utensils and the like for the grill.
OEM Deflector with OEM Grates:
OEM Lower Grate with Half Moon Deflector and OEM Half Moon Grate:
OEM Deflector and Lower Grate with (2) Half Moon Deflectors and Upper Rack:
Same as above with Cast Iron Griddle ready for pizza:
I just acquired a primo from a friend who was downsizing. I am replacing and upgrading components and really wanted an oven style/fiberglass or woven metal type gasket vs. nomex. This just seems like a cleaner option for the grill surface.
I read a story about someone using this type of gasket (thicker than the standard gasket) so they only needed to gasket the lid - not the cooking surface (limited grease and organic matter on a grate level gasket).
