What accessories should I buy? First time buyer. Also Cafune referral code?

Hello I was deciding between the flair and robot and want to go with the robot because of the workflow. I have a bambino plus but I want more shot control so I want to join the manual club. I plan to buy off the cafune site when it is back in stock. I wanted to know if anyone has a referral code by chance. What accessories should I buy besides an extra basket?
