So returning to stations to buy certain ingredients to build myself some equipment, I have noticed how long it takes to build simple things. I've also noticed now that all red stations sell price is always exactly half or less of the item buy price, which in itself defeats what the devs were trying to eliminate using cool downs -- people buying materials, crafting selling, get rich repeat.  With everything half the sell price it's already made crafting for profit in stations totally redundant, so why keep the cool down penalty at all?  I think you've already eliminated that problem right there in adjusting prices..
