I really don't understand how you can think that the "reasonable" price is some price you make up in your head, while the price that people are willing to pay is somehow overinflated. All the explanation you need is right in your initial post: You spent 7-8 weeks doing back-to-back UWT missions and STILL didn't get these schematics. For me, my time is worth more than that - I would never spend my time that way. I would happily pay a high price to avoid having to grind those missions. For you, obviously, you would rather give up the time and keep the money.
So it's simple: if you value the money more than the time, do the UWT missions. If you value the time more than the money, pay the reseller. You charging less for it doesn't change the inherent rarity - and hence value - of the item.
Man the worst failure of our education system, by a longshot, is the failure to teach even basic principles of economics.
I have to agree with this post. A couple weeks ago I got an orange belt schematic from UWT that I already knew. I listed it on the GTN at 75k and it sold within an hour. According to the OP, I should have listed it for a couple credits to help out my other crafters?
