Im gonna take a different stance and probably catch some flak.
Save your money! Ive had three different competition guys put it to me this way...
"They are over priced kettles!!"
all three said the exact same, thing they have no affiliation with each other. One of the guys owns a BBQ store, and he talked me out of buying a new Primo Oval XL for 1800.00, so he actually lost a sale providing me his honest opinion since I was wanting a smoker.
I have to agree with them, I do own a Primo Oval Jr that i bought for $225 off CL, I sure am glad I didnt spend 1800, been using it for a couple years, honestly I dont see any improvement in my food. I can achieve the same results with a kettle when it comes to grilling, I use my WSM for smoking which does a better job of smoking than the primo. Kamados are efficient though.
You need to ask yourself this. What are you going to use a Kamado for?
1) Smoking? if so ,there are way better smokers
2) grilling? you already have a grill, you can hit a 1000 degrees on a kettle
3) Baking? well this is where the kamado does better than a kettle, personally I use my oven for baking.
4) all of the above? well, you have a grill, you dont have a true smoker and I assume you have an oven but maybe you really want to bake on a kamado.
I would buy a smoker since you already have the other tools
