I can vouch for the Vision kamado. Its an excellent cooker and they have excellent customer service speaking from my experience as well. I have the Vision Pro from Home Depot and my bro has the classic from Costco that I bought for him as a gift. Two of my buddies picked up Visions after they saw mine and we're all happy. Comes with all the extras and a cover. BTW they are showing up at Costcos here again already. If you're on a strict budget though I wouldnt dismiss the Akorn. Good luck!
