I was thinking I might be cool for Ivan to upgrade your components for payment. I'm bad at coming up with balanced numbers but for example trade [1 engine lvl1; 10 broccoli; 10 pineapple] for [engine level 5]. Or [thruster lvl1; 40 broccoli; 40 pineapple; 20 orange] for [thruster lvl5]

The extra items probably don't make sense but I hope my suggestion does.
